Description

Technical Field

[0001] The present invention relates to the technical field of road and bridge construction, and in particular to a supporting device and method for road and bridge construction. Background Art

[0002] The road and bridge construction support system is an important part of bridge construction. It is used to provide necessary temporary support and stability during the bridge construction process. It is mainly used for the support of the pouring, assembly and construction stages of the bridge structure to prevent construction errors caused by concrete pouring or deformation of the bridge structure, ensure construction safety and ensure structural stability. Its main support types include formwork support system, pier support system, erection support system, slipform support system, steel pipe support system and temporary support platform; At present, after the construction of the bridge piers is completed, the bridge frame will be built above the piers. Since most of the bridge frame is in a suspended state, the bridge frame between the two piers needs to use multiple supporting devices to support the suspended bridge frame; The current support device is usually composed of a plurality of support pipes connected end to end, with flanges fixed at both ends of the support pipes, and two adjacent flanges are connected to each other by bolts. The flanges in contact with the mounting platform are fixed to the mounting platform by bolts, so that the bridge frame can be supported. However, most of the existing technologies support the bridge frame by matching and splicing support pipes of different lengths, or pads are placed on the top support pipes to adapt to the height of the bridge frame. Although the support pipes and pads have various specifications, they do not have a small correction of the support height, which causes the bridge frame to bend and affects the quality of the bridge frame. Meanwhile, the prior art uses bolts to achieve relative fixation between the two flanges. However, the use of bolts to fix the two flanges not only requires the use of external tools, but also increases the labor intensity of construction workers due to the large number of bolts, and also reduces the construction efficiency. Furthermore, when the prior art supports a bridge frame that is inclined in the vertical direction, the contact area between the supporting device and the bridge frame is small, which reduces the supporting effect. Summary of the invention

[0003] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0004] In view of the fact that most of the above-mentioned existing technologies support the bridge frame by splicing support tubes of different lengths, or padding blocks are placed on the top support tubes to adapt to the height of the bridge frame. Although the support tubes and pads are available in various specifications, there is no small correction of the support height, which causes the bridge frame to bend and affects the quality of the bridge frame. A support device for road bridge construction is proposed.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a support device for road and bridge construction, comprising a height adjustment mechanism, comprising a moving block and adjustment blocks symmetrically arranged on the left and right sides of the moving block; a support mechanism arranged above the moving block, comprising a top pipe and a bottom pipe distributed in the up-down direction and coaxially arranged, a plurality of support pipes are coaxially arranged between the top pipe and the bottom pipe, the lower ends of the support pipes and the top pipes are both threadedly connected with connecting sleeves, the lower sides of the connecting sleeves are plugged into the corresponding support pipes and the bottom pipes, the lower ends of the top pipes and the support pipes are both fixed with fixing plates, and the upper ends of the support pipes and the bottom pipes are both fixed There is a mounting plate, the lower wall of which is fixed with U-shaped bars in a circular array, mounting sleeves are arranged below the U-shaped bars on the outside of the corresponding support tubes and bottom tubes, the open side of the U-shaped bars is fixed with baffles distributed in a circular array and adapted to the U-shaped bars on the upper wall of the mounting sleeve corresponding to the mounting sleeve, a worm gear is fixed to the outer peripheral wall of the mounting sleeve, one side of the worm gear is meshingly connected with a worm, a fixing sleeve is arranged in cooperation with the internal clearance of the mounting sleeve, a flange is fixed below the mounting sleeve corresponding to the outside of the fixing sleeve; and an abutment mechanism arranged above the top tube, comprising a top plate fixed to the upper end of the top tube and an abutment block arranged above the top plate and having an arc-shaped lower wall.

[0006] As a preferred solution of the support device for road and bridge construction of the present invention, the left and right side walls of the moving block are symmetrically provided with fitting surfaces that are fitted with and slidably connected to the moving block, and the two side walls of the moving block are symmetrically fixed with guide strips with convex cross-sections, and the side walls of the adjustment block corresponding to the position of the guide strip are provided with guide grooves that are adapted to the guide strip.

[0007] As a preferred solution of the supporting device for road and bridge construction of the present invention, a bottom plate is arranged below the adjusting block, the adjusting block is slidably connected to the bottom plate, and a plurality of mounting holes are opened on the bottom plate.

[0008] As a preferred solution of the present invention, a supporting device for road and bridge construction, wherein: the internal threads of the two adjusting blocks are connected with a screw rod, the thread directions of the outer peripheral walls on both sides of the screw rod are opposite to achieve driving the two adjusting blocks to approach or move away from each other along the axial direction of the screw rod, side plates are fixed to the upper walls of the outer corresponding bottom plates at both ends of the screw rod, the screw rod is rotatably connected to the side plates through bearings, a rocker is fixed to one end of the screw rod, and a limit strip with an inverted convex cross section is symmetrically fixed to the upper wall of the bottom plate, and the adjusting block is slidably connected to the limit strip.

[0009] The beneficial effects of a support device for road and bridge construction of the present invention are as follows: by rotating the screw rod, since the screw rod is threadedly connected to the two adjusting blocks, and the threads on both sides of the screw rod are in opposite directions, when the screw rod rotates, the adjusting blocks are driven to move closer to or farther away from each other, thereby driving the moving blocks to rise or fall accordingly, and finally causing the supporting mechanism and the abutting mechanism to rise or fall accordingly, thereby achieving a small correction to the supporting height. In this way, the supporting height can be adjusted slightly, which can avoid bending of the bridge frame and improve the quality of the bridge frame.

[0010] In view of the above-mentioned prior art that uses bolts to achieve relative fixation between two flanges, however, the use of bolts to fix the two flanges not only requires the use of external tools, but also increases the labor intensity of construction workers due to the large number of bolts, and also reduces the construction efficiency. Therefore, a support device for road and bridge construction is further improved.

[0011] As a preferred solution of the support device for road and bridge construction of the present invention, the bottom tube is fixedly connected to the moving block, the connecting sleeve is clearance-matched with the corresponding supporting tube and bottom tube, the outer peripheral walls of the corresponding supporting tube and bottom tube on one side of the connecting sleeve are threadedly connected with bolts, the inner ends of the bolts are abutted against the corresponding connecting sleeve, positioning rings are fixed to the inner walls of the corresponding supporting tube and bottom tube above the connecting sleeve, and through holes are symmetrically opened on the lower side of the connecting sleeve.

[0012] As a preferred solution of the support device for road and bridge construction of the present invention, wherein: the lower side of the fixed sleeve is evenly threaded with screws along the circumferential direction of the fixed sleeve, the screws are threadedly connected to the corresponding top pipe and support pipe, a cross plate is fixed on the corresponding fixed sleeve below the worm, end plates are fixed at both ends of the upper wall of the cross plate, the worm is rotatably connected to the end plate through a bearing, and a rocker wheel 2 is fixed at one end of the worm.

[0013] As a preferred solution of the present invention, a supporting device for road and bridge construction, wherein: the baffle is arranged in an L shape, a slope is provided at one end of the baffle close to the corresponding U-shaped bar, chamfers are symmetrically provided at both ends of the lower wall of the U-shaped bar, and a through groove adapted to the U-shaped bar is provided on the corresponding mounting plate at the position where the U-shaped bar is located.

[0014] Another beneficial effect of the support device for road and bridge construction of the present invention is: by passing the U-shaped bar on the fixed plate through the through groove on the mounting plate to be connected, after the cross plate contacts the mounting plate, by rotating the corresponding worm, the mounting sleeve is rotated with the cooperation of the worm gear, thereby driving the retaining bar to rotate until it abuts against the corresponding U-shaped bar, thereby achieving a relatively fixed connection between the mounting plate and the fixed plate. Compared with the prior art, the relative fixation between the adjacent fixed plate and the mounting plate is achieved by the cooperation of the U-shaped bar and the corresponding retaining bar, and fast fixation can be achieved without the use of bolts, and the fixing effect is good. No external tools are required, and the labor intensity of construction personnel is reduced.

[0015] In view of the problem that when the above-mentioned prior art supports a bridge frame that is inclined in the vertical direction, the contact area between the supporting device and the bridge frame is small, which reduces the supporting effect, a further improvement is made to a supporting device for road and bridge construction.

[0016] As a preferred solution of the support device for road and bridge construction of the present invention, the lower wall of the abutment block is evenly fixed with upper positioning teeth, the upper wall of the top plate is evenly fixed with lower positioning teeth partially staggered with the upper positioning teeth, L-shaped limit rods are symmetrically arranged on the front and rear sides of the top plate, and an elastic member is provided on the outer sleeve of the corresponding limit rod above the top plate.

[0017] As a preferred solution of the present invention, a supporting device for road and bridge construction, wherein: a baffle is fixed to the lower end of the limit rod, a limit sleeve that matches the gap with the limit rod is fixed to the lower wall of the top plate corresponding to the outside of the limit rod, a circular plate is fixed to the upper end of the elastic member corresponding to the outside of the limit rod, the abutment block is rotatably connected to the limit rod through a bearing, and an anti-slip pad is fixed to the upper wall of the abutment block.

[0018] Another beneficial effect of the support device for road and bridge construction of the present invention is: under normal conditions, the abutment block is separated from the top plate under the action of the elastic member, and when the supported surface of the bridge frame is inclined, the height adjustment mechanism is operated to rise to drive the abutment mechanism to rise. Since the abutment block and the top plate can rotate relative to each other, when supporting the inclined bridge frame, the upper wall of the anti-slip pad in the abutment block adaptively fits the supported surface of the bridge frame, thereby increasing the supporting area of ​​the bridge frame and achieving a better supporting effect on the bridge frame.

[0019] The present invention also provides a supporting method for a road and bridge construction supporting device, and the supporting operation is performed according to the following steps: S1. First, place the height adjustment mechanism at the location to be installed, and then use bolts to pass through the installation holes to fix the base plate to the installation platform; S2, operate the support tube to make the U-shaped bar fixed to the support tube pass through the through groove in the mounting plate on the adjacent support tube, at this time, the connecting sleeve is inserted into the adjacent support tube, and then operate the second rocker to drive the corresponding worm to rotate, and drive the blocking bar to move toward the adjacent U-shaped bar and abut against it with the cooperation of the worm gear; S3, repeating step S2 until the length of the connection between the multiple support tubes reaches the required length, operating the U-shaped bar fixed relatively to the top tube to be inserted into the through groove on the adjacent mounting plate, and then operating the corresponding rocker second to drive the corresponding worm, so that under the action of the corresponding worm gear, the corresponding stopper bar abuts against the corresponding U-shaped bar to achieve relative fixation of the abutment mechanism and the support mechanism; S4, then use the lifting equipment to lift the abutment mechanism and the support mechanism, so that the U-shaped bar at the bottom passes through the through slot on the mounting plate fixed to the bottom tube, and then operate the corresponding second rocker to drive the corresponding worm to rotate, so that under the action of the corresponding worm gear, the corresponding stop bar abuts against the corresponding U-shaped bar, so that the support mechanism and the height adjustment mechanism are relatively fixed; S5. Finally, the screw rod is rotated by operating the rocker, so that the two adjustment blocks are close to each other, driving the moving block to rise, thereby raising the supporting mechanism and the abutting mechanism until the upper wall of the anti-slip pad on the abutting block contacts the supported surface, and the upper positioning teeth and the lower positioning teeth are partially staggered.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Example 1

[0036] Reference Figure 1 , Figure 2 and Figure 3 , which is the first embodiment of the present invention, provides a support device for road and bridge construction, which drives the two adjustment blocks 103 to move closer to or away from each other by rotating the screw 104, so that the moving block 101 rises or falls accordingly, thereby achieving the purpose of making a small adjustment to the support height of the bridge frame.

[0037] Specifically, it includes a height adjustment mechanism 100, including a moving block 101 and adjustment blocks 103 symmetrically arranged on the left and right sides of the moving block 101, and the contact surfaces of the adjustment block 103 and the moving block 101 are smooth surfaces; a support mechanism 200 arranged above the moving block 101, including a top tube 204 and a bottom tube 208 distributed in the up and down directions and coaxially arranged, and the top tube 204, the bottom tube 208 and the support tube 205 can be made of the same material; and, an abutment mechanism 300 arranged above the top tube 204, including a top plate 302 fixedly arranged at the upper end of the top tube 204 and an abutment block 301 arranged above the top plate 302 and with an arc-shaped lower wall, and the upper wall of the abutment block 301 is a plane.

[0038] Read in detail Figure 2 and Figure 3 As shown, the left and right side walls of the moving block 101 are symmetrically provided with fitting surfaces that fit with the moving block 101 and are slidably connected with the moving block 101, so that the moving block 101 can move up and down accordingly to achieve lifting and lowering. The two side walls of the moving block 101 are symmetrically fixed with guide bars 101a with convex cross sections, and the side walls of the adjustment block 103 corresponding to the position of the guide bars 101a are provided with guide grooves 103a adapted to the guide bars 101a. In the above arrangement, the guide bar 101a is located in the corresponding guide groove 103a for movement. The cooperation between the guide bar 101a and the guide groove 103a prevents the moving block 101 from moving horizontally and prevents the moving block 101 from being separated from the adjusting block 103. The guide bar 101a and the corresponding adjusting block 103 are loosely matched.

[0039] Read in detail Figure 2 and Figure 3 As shown, a base plate 102 is provided below the adjusting block 103, and the adjusting block 103 is slidably connected to the base plate 102. A plurality of mounting holes 102c are provided on the base plate 102. The base plate 102 is fixed to the mounting platform by passing fasteners through the mounting holes 102c. The fasteners can be expansion bolts, and the mounting platform can be a concrete platform.

[0040] Read in detail Figure 2 and Figure 3 As shown, the internal threads of the two adjusting blocks 103 are connected with screw rods 104, and the thread directions of the outer peripheral walls on both sides of the screw rods 104 are opposite to each other so as to drive the two adjusting blocks 103 to approach or move away from each other along the axis direction of the screw rods 104. The outer sides of the two ends of the screw rods 104 correspond to the upper wall of the bottom plate 102 and are fixed with side plates 102a, which are used to enable the screw rods 104 to rotate at a fixed position. The screw rods 104 are rotatably connected with the side plates 102a through bearings. A rocking wheel 104a is fixed at one end of the screw rods 104. The rocking wheel 104a is operated to rotate the screw rods 104. The upper wall of the bottom plate 102 is symmetrically fixed with limit strips 102b with an inverted convex cross section, so that the adjusting blocks 103 can only move left and right, and at the same time, the adjusting blocks 103 are prevented from being separated from the bottom plate 102. The adjusting blocks 103 are slidably connected with the limit strips 102b. With the above arrangement, when the screw rod 104 rotates, the two adjusting blocks 103 are driven to move away from or closer to each other. At this time, the guide bar 101 a and the corresponding adjusting block 103 move relative to each other, and the adjusting block 103 and the bottom plate 102 move relative to each other.

[0041] Furthermore, in order to reduce the weight and cost of the height adjustment mechanism 100, the adjustment block 103 and the moving block 101 are hollowed out while ensuring structural stability. In addition, when actually supporting the bridge frame, hydraulic cylinders or pads can be placed on the upper wall of the base plate 102 in front of and behind the screw 104, and the upper end of the hydraulic cylinder or pad is abutted against the lower wall of the moving block 101, so as to reduce the pressure on the screw 104 by using the hydraulic cylinder or pad. Example 2

[0042] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9, which is the second embodiment of the present invention, is based on the previous embodiment. The difference from the previous embodiment is that the U-shaped bar 201a is passed through the through slot 202a on the installation disk 202 to be installed, and the worm 207 is used to rotate, and the blocking bar 203a is brought into contact with the U-shaped bar 201a under the action of the worm gear 203b. The cooperation between the U-shaped bar 201a and the blocking bar 203a is used to realize the rapid installation of the fixed disk 201 and the installation disk 202, which reduces the labor intensity of the construction workers and improves the construction efficiency.

[0043] For details, please read Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, a plurality of support tubes 205 are coaxially arranged between the top tube 204 and the bottom tube 208. Different numbers of support tubes 205 are spliced ​​together to support the bridge skeletons of different heights. The lower ends of the support tubes 205 and the top tube 204 are threadedly connected with connecting sleeves 211. The lower side of the connecting sleeve 211 is inserted into the corresponding support tubes 205 and the bottom tube 208. The connecting sleeve 211 can enhance the anti-tilting effect between two adjacent support tubes 205 and between the support tube 205 and the top tube 204. 04 and the lower end of the support tube 205 are fixed with a fixing plate 201, and the fixing plate 201 can be fixed with the corresponding support tube 205 and the top tube 204 by welding. The upper ends of the support tube 205 and the bottom tube 208 are fixed with a mounting plate 202, and the mounting plate 202 can be fixed with the corresponding support tube 205 and the bottom tube 208 by welding. Preferably, the mounting plate 202 has the same specifications as the fixing plate 201, and the lower wall of the fixing plate 201 is fixed with a U-shaped strip 201a in a circular array, and the lower part of the U-shaped strip 201a The outer sides of the corresponding support tubes 205 and bottom tubes 208 are provided with mounting sleeves 203 to provide a fixing platform for the stopper 203a. The upper wall of the mounting sleeve 203 corresponding to the open side of the U-shaped strip 201a is fixed with stoppers 203a distributed in a circumferential array and adapted to the U-shaped strip 201a. The cooperation between the stoppers 203a and the U-shaped strip 201a realizes the rapid fixing between the fixing plate 201 and the mounting plate 202. The outer peripheral wall of the mounting sleeve 203 is fixed with a worm gear 203b, and one side of the worm gear 203b is meshedly connected with a worm 207. When the worm 207 rotates, the mounting sleeve 203 rotates with the cooperation of the worm gear 203b, and finally the stop bar 203a rotates. The internal clearance of the mounting sleeve 203 is matched with a fixing sleeve 212, and the fixing sleeve 212 is matched with the corresponding support tube 205 and the bottom tube 208. A flange 212a is fixed below the mounting sleeve 203 corresponding to the outside of the fixing sleeve 212. The lower wall of the mounting sleeve 203 contacts the upper wall of the flange 212a, and the flange 212a is used to provide a support platform for the mounting sleeve 203 when it rotates. The above arrangement, by rotating the worm 207, rotates the mounting sleeve 203 with the cooperation of the worm gear 203b, drives the retaining bar 203a to rotate, and makes the retaining bar 203a contact or disengage with the corresponding U-shaped bar 201a, thereby realizing rapid disassembly and assembly between the fixing plate 201 and the mounting plate 202.

[0044] Read in detail Figure 4 , Figure 6 and Figure 7 As shown, the bottom tube 208 is fixedly connected to the moving block 101, and the connecting sleeve 211 is clearance-matched with the corresponding support tube 205 and the bottom tube 208 to avoid shaking. The outer peripheral wall of the corresponding support tube 205 and the bottom tube 208 on one side of the connecting sleeve 211 is threadedly connected with a bolt 210, and the inner end of the bolt 210 abuts against the corresponding connecting sleeve 211. The bolt 210 can prevent the connecting sleeve 211 from self-rotating. The upper part of the connecting sleeve 211 is fixed with a positioning ring 209 corresponding to the inner wall of the support tube 205 and the bottom tube 208 to limit the depth of the connecting sleeve 211 inside the support tube 205 and the top tube 204, so as to prevent the connecting sleeve 211 from entering the support tube 205 and the top tube 204 too deeply or too shallowly. The lower side of the connecting sleeve 211 is symmetrically provided with perforations 211a to facilitate the passage of rod-shaped objects. With the above arrangement, when the connecting sleeve 211 is worn, the bolt 210 is operated to be separated from the connecting sleeve 211 . At this time, a rod-shaped object is inserted into the through hole 211 a to rotate the connecting sleeve 211 , thereby realizing the disassembly and assembly of the connecting sleeve 211 .

[0045] Read in detail Figure 4 , Figure 8 and Fig. 9 As shown, the lower side of the fixing sleeve 212 is evenly threadedly connected with screws 212b along the circumferential direction of the fixing sleeve 212, and the screws 212b are threadedly connected with the corresponding top pipe 204 and the support pipe 205, and the fixing sleeve 212 is fixed to the top pipe 204 and the support pipe 205 by the screws 212b. A horizontal plate 206 is fixed to the corresponding fixing sleeve 212 below the worm 207, and end plates 206a are fixed at both ends of the upper wall of the horizontal plate 206. The worm 207 is rotatably connected with the end plate 206a through a bearing, and a rocker 207a is fixed to one end of the worm 207; With the above arrangement, the worm 207 can be rotated by operating the second rocking wheel 207a, thereby rotating the mounting sleeve 203 under the action of the worm gear 203b.

[0046] Read in detail Figure 8 and Fig. 9As shown, the blocking bar 203a is arranged in an L shape. Preferably, the upper wall of the blocking bar 203a is slidably connected to the corresponding mounting plate 202 above it. In order to prevent the blocking bar 203a from being subjected to upward force and passing through the through groove 202a, the length of the blocking bar 203a is greater than the length of the through groove 202a, that is, when two adjacent support tubes 205 are in a relatively fixed state, part of the upper wall of the blocking bar 203a is always in contact with the lower wall of the corresponding mounting plate 202, and the blocking bar 203a is provided with an inclined surface at one end close to the corresponding U-shaped bar 201a, and the inclined surface is used to make The lower wall of the installation sleeve 203 contacts the upper wall of the flange 212a to avoid the gap between the installation sleeve 203 and the flange 212a, which may cause the two support tubes 205 to shake after installation. The two ends of the lower wall of the U-shaped bar 201a are symmetrically chamfered, and the chamfers are inclined to facilitate the U-shaped bar 201a to pass through the through groove 202a. The installation plate 202 corresponding to the position of the U-shaped bar 201a is provided with a through groove 202a adapted to the U-shaped bar 201a, providing a channel for the U-shaped bar 201a to pass through the corresponding installation plate 202; With the above arrangement, during the installation process of the fixed disk 201 and the mounting disk 202, the U-shaped bar 201a is passed through the through groove 202a and the upper wall of the mounting disk 202 is brought into contact with the lower wall of the fixed disk 201. The worm 207 is rotated to make the blocking bar 203a enter the open side of the U-shaped bar 201a until the blocking bar 203a is brought into contact with the U-shaped bar 201a and a certain pressure is maintained, thereby achieving relative fixation of the fixed disk 201 and the mounting disk 202.

[0047] Furthermore, in order to further improve the stability of the support device for road and bridge construction during use, two adjacent support mechanisms 200 are fixedly connected by a connecting rod. Specifically, the two ends of the connecting rod are fixedly connected to the corresponding support pipe 205 by bolts. This method is a commonly used reinforcement method in the support construction of roads and bridges. It is a prior art and will not be elaborated here. Example 3

[0048] Reference Figure 1 , Fig.10 and Fig.11 , which is the third embodiment of the present invention, is based on any of the above embodiments, and is different from the above embodiments in that: under normal conditions, under the action of the elastic member 304, the abutment block 301 is not in contact with the top plate 302. When supporting the inclined bridge frame, the abutment block 301 can rotate and adaptively fit with the inclined bridge frame to increase the contact area to improve the supporting effect.

[0049] For details, please read Fig.10 and Fig.11As shown, the lower wall of the abutment block 301 is evenly fixed with upper positioning teeth 301b, and the upper wall of the top plate 302 is evenly fixed with lower positioning teeth 302a that are partially staggered with the upper positioning teeth 301b. The arrangement of the upper positioning teeth 301b and the lower positioning teeth 302a can prevent the abutment block 301 from sliding in the horizontal direction. L-shaped limiting rods 303 are symmetrically arranged on the front and rear sides of the top plate 302 to achieve horizontal limiting of the abutment block 301. An elastic member 304 is sleeved on the outer portion of the corresponding limiting rod 303 above the top plate 302. The elastic member 304 can be a spring, so that when no object is supported, the abutment block 301 and the top plate 302 are in a disengaged state. A baffle 303a is fixed to the lower end of the limit rod 303 to prevent the limit rod 303 from detaching from the top plate 302, thereby providing a limiting effect for the limit rod 303. A limit sleeve 302b that is clearance-matched with the limit rod 303 is fixed to the outside of the limit rod 303 corresponding to the lower wall of the top plate 302, thereby further improving the anti-tilt ability of the limit rod 303. A circular plate 303b is fixed to the upper end of the elastic member 304 corresponding to the outside of the limit rod 303. The abutment block 301 is rotatably connected to the limit rod 303 through a bearing, so that the abutment block 301 can rotate relative to the limit rod 303. An anti-slip pad 301a is fixed to the upper wall of the abutment block 301. When supporting the bridge frame, the anti-slip pad 301a contacts the supported surface of the bridge frame.

[0050] Furthermore, the abutment block 301 is hollowed out to reduce its own weight and facilitate movement. Example 4

[0051] This embodiment is the fourth embodiment of the present invention. This embodiment provides a supporting method for a road and bridge construction supporting device. The supporting operation is performed according to the following steps: S1. First, place the height adjustment mechanism 100 at the location to be installed, and then use bolts to pass through the installation holes 102c to fix the base plate 102 to the installation platform; S2, operate the support tube 205 to make the U-shaped bar 201a fixed to the support tube 205 pass through the through slot 202a in the mounting plate 202 on the adjacent support tube 205, and then the connecting sleeve 211 is inserted into the adjacent support tube 205, and then operate the second rocker 207a to drive the corresponding worm 207 to rotate, and drive the blocking bar 203a to move toward and abut against the adjacent U-shaped bar 201a with the cooperation of the worm gear 203b; S3, repeating step S2 until the length of the connection between the plurality of support tubes 205 reaches the required length, operating the U-shaped bar 201a fixed relatively to the top tube 204 to be inserted into the through slot 202a on the adjacent mounting plate 202, and then operating the corresponding rocker 207a to drive the corresponding worm 207, so that under the action of the corresponding worm gear 203b, the corresponding stop bar 203a is abutted against the corresponding U-shaped bar 201a to achieve relative fixation of the abutment mechanism 300 and the support mechanism 200; S4, then use the lifting equipment to lift the abutment mechanism 300 and the support mechanism 200, so that the U-shaped bar 201a at the bottom passes through the through slot 202a on the mounting plate 202 fixed to the bottom tube 208, and then operate the corresponding rocker 207a to drive the corresponding worm 207 to rotate, so that under the action of the corresponding worm gear 203b, the corresponding blocking bar 203a is abutted against the corresponding U-shaped bar 201a, so that the support mechanism 200 and the height adjustment mechanism 100 are relatively fixed; S5. Finally, by operating the rocker 104a to rotate, the screw rod 104 is driven to rotate, so that the two adjustment blocks 103 are moved closer to each other, driving the moving block 101 to rise, thereby raising the supporting mechanism 200 and the abutting mechanism 300, until the upper wall of the anti-slip pad 301a on the abutting block 301 contacts the supported surface, and the upper positioning teeth 301b and the lower positioning teeth 302a are partially staggered.
