Description

Technical Field

[0001] The present invention belongs to the technical field of bridge construction equipment, and in particular relates to a pile driving and moving guiding device for bridge construction under harsh slope conditions. Background Art

[0002] With the development of urbanization and railway transportation, more and more bridges are being built. Bridges can cross obstacles and ensure the smooth passage of vehicles. During the construction of bridges, the stability of the bridge columns is crucial. They cannot be displaced horizontally, tilted, or settled. Sometimes it is necessary to provide certain protection for the river slopes to improve their stability. However, there are still some shortcomings in the use of existing slope protection devices. For example, the existing slope protection devices generally directly drive the positioning rods into the soil to fix the protection net. The positioning rods and the soil have poor bite ability, resulting in low overall stability of the subsequent protection net, which reduces the practicality of the device. When the existing slope protection devices are used in combination, there is a lack of certain connections between adjacent protection devices, which makes it impossible to conveniently position the device during subsequent splicing, and reduces the integrity of the device.

[0003] Bridges are built on foundations. If the foundation is stable, the construction of the bridge is much easier. If the foundation is unstable, that is, a soft foundation, the foundation must be pre-treated before the bridge is built to improve its stability. The biggest characteristics of a soft foundation are loose soil, high water content, and poor bearing capacity, which are prone to settlement and slippage. If this foundation is located on a slope, the settlement and slippage will be more serious, posing a greater challenge to bridge construction. A typical example of a soft foundation located on a slope is a road bridge built in a river valley. There are many such construction scenarios in southern my country. During the piling construction process on the river slope, anti-landslide treatment of the river slope should also be considered at the same time as the bridge pile foundation construction. Existing anti-slip piles are a common reinforcement structure in slope reinforcement projects. Anti-slip piles are arranged at different positions and depths on the slope and are generally driven vertically. Anti-slide piles penetrate the landslide and are embedded deep within the sliding bed. The pile body transmits the landslide thrust from the upper portion of the pile to the soil or rock mass of the sliding bed below the pile. The lateral resistance of the pile body embedded in the sliding bed rock and soil balances the sliding thrust of the loaded section of the pile body, thus ensuring the stability of the reinforced slope. Pile driving relies on large-scale machinery. Existing large-scale pile foundation equipment is primarily used for bridge pile foundation construction. However, when considering landslide pile construction, the expanded scope of construction leads to difficulties in existing pile driving. Summary of the Invention

[0004] To address the problem of local slopes on river slopes where large machinery cannot penetrate deep into the slopes for construction, the present invention provides a mobile guiding device for pile driving under harsh conditions on bridge slopes. Tracks are laid using slope walkways and a vehicle frame is used to move pile driving and mobile electric hammers to the far end for guided construction, eliminating the need for large equipment to be moved over long distances for construction.

[0005] The solution adopted by the present invention to solve its technical problems is: a pile-driving mobile guiding device for harsh conditions on the slope of bridge construction, including a frame, inner track wheels, double parallel C-shaped tracks and a stable clamping mechanism, the double parallel C-shaped tracks are fixed to the ground foundation, the inner track wheels located at the bottom of the frame are respectively inserted into the corresponding C-shaped tracks, a bracket is fixed on the base of the frame, and a stable clamping mechanism is respectively fixed to the inner middle of the four side walls of the bracket, each stable clamping mechanism includes a fixed seat, an outer pressure plate, an upper connecting plate and a lower connecting plate, the two ends of the upper connecting plate and the lower connecting plate are respectively hinged to the upper end of the fixed seat and the lower end of the outer pressure plate, so that the height of the outer pressure plate is always kept higher than the height of the fixed seat, the four outer pressure plates of the four groups of stable clamping mechanisms are combined into the four sides of a quadrangular prism, and a downward driving mechanism is provided to drive the four outer pressure plates to move downward.

[0006] First, the end fixing frame is used as the basic guide frame, and the two end fixing piles are respectively pressed into the fixing channels on both sides of the end fixing frame to fix the end fixing frame. The two C-shaped rails are respectively fixedly connected on both sides of the end fixing frame so that the proximal ends of the two rails are fixed. Connecting plates are respectively fixed in the middle and ends of the two C-shaped rails.

[0007] A tension spring is connected at the upper end pin shaft position of the lower connecting plate and the lower end pin shaft position of the upper connecting plate.

[0008] The C-shaped track includes a base and an upper C-shaped track groove, which includes two side walls and a groove on the top, and shoulder plates on both sides of the groove; the inner track wheel is a double parallel wheel, with a rotating shaft in the middle, and an axle bracket installed on the middle rotating shaft, and the axle bracket is fixed to the bottom of the frame; the axle bracket is led out from the groove of the C-shaped track, and the double parallel wheels are respectively located on the lower sides of the two shoulder plates.

[0009] The downward driving mechanism includes a movable inner frame and a swing frame assembly. The movable inner frame includes an upper horizontal frame and a lower horizontal frame of the inner frame. A vertical column is connected between the upper horizontal frame and the lower horizontal frame. The middle parts of the upper horizontal frame and the lower horizontal frame are connected with parallel limit plates. The upper connecting plate and the lower connecting plate of each stable clamping mechanism are respectively installed in the corresponding parallel limit plates. The upper horizontal frame of the inner frame is located above the upper connecting plate of each stable clamping mechanism, and the lower horizontal frame of the inner frame is located below the lower connecting plate of each stable clamping mechanism. A counterweight ring is fixed below the lower horizontal frame of the inner frame. The swing frame assembly is used to drive the counterweight ring to rise or fall.

[0010] The beneficial effects of the present invention are as follows: a pile driving and moving guiding device for bridge construction under harsh slope conditions is adopted, which enables the construction machinery to adapt to driving and transferring construction on narrow slope spans or horse trails through its narrow body during slope pile driving construction. The construction machinery can also move and construct on its own or be towed during the construction process.

[0011] The four internal pressure plates of the four groups of stable clamping mechanisms in the equipment are combined to form the four sides of a quadrangular prism. When the lower end of the pile is inserted into the inner side of the four internal pressure plates, the downward pressure drive mechanism is used to press each internal pressure plate against the four sides of the pile. The side walls around the pile generate a downward friction force on each internal pressure plate. The more each internal pressure plate moves downward, the greater the clamping force. The gravity of the pile and the mobile electric hammer at its upper end, combined with the pressure of each internal pressure plate, form a supporting relationship that prevents it from sliding downward. After the frame moves into position, the downward pressure drive mechanism releases the pressure on each internal pressure plate. Each internal pressure plate moves upward and outward under the action of the corresponding tension spring, causing the pile to fall to the ground. When the four internal pressure plates are spread outward a small distance, although the support for the pile is released, they can still form a vertical channel, which has the function of guiding the pile and preventing the pile from tilting due to the high-frequency impact of the electric hammer.

DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings and examples.

[0023] Example 1: A Figure 1 The pile driving mobile guiding device shown in the figure is designed to solve the problem that large machinery cannot penetrate deep into the river slope with a certain slope during construction. The pile driving mobile guiding device mainly includes a frame 1, inner track wheel 3, C-shaped track 19 and a stabilizing clamping mechanism 5. The pile driving mobile guiding device cooperates with the crane construction. The foundation is leveled along the river slope with the crane as the center, or the original horse road is used as the foundation. Double parallel C-shaped tracks 19 are laid on the foundation. The frame 1 and the working unit on it are located on the upper side of the C-shaped track 19 and move along the track. The mobile electric hammer 30 (such as Figure 7 After the pile is hoisted, the clamp at the lower end of the mobile hammer 30 is used to clamp the end of the pile, and the mobile hammer 30 and the pile are hoisted together to form an upright position, and then the lower end of the pile is inserted into the Figure 2 On the inner side of each stable clamping mechanism 5, each clamping mechanism is controlled to clamp and fix the pile, and then transferred to the pile lowering position for press-fitting construction.

[0024] Figure 2 The internal structure of the pile driving mobile guide device is shown. The middle part of the frame 1 is the main working unit. The frame 1 is extended with auxiliary frames on the front and rear sides along the travel direction. Inner track wheels 3 are installed under the frame 1 and the auxiliary frames respectively. Each inner track wheel is matched and installed in the corresponding C-shaped track 19. Figure 9As shown, at a position close to the crane, first use the end fixing frame 26 as the basic guide frame, hoist the mobile electric hammer 30 carrying the end fixing pile 27, and press the two end fixing piles into the fixed channels on both sides of the end fixing frame 26, so that the end fixing frame 26 is fixed. Two C-shaped rails 19 are fixedly connected on both sides of the end fixing frame 26, so that the proximal ends of the two rails are fixed. Connecting plates 28 are fixed to the middle and ends of the two C-shaped rails 19 to ensure that the two are always parallel and fixed. There is a protruding fixing seat at the bottom of the distal rail, which is fixed to the bottom layer by an anchor rod. It is also possible to further consider laying sleepers 47 of a certain height at the bottom of the two C-shaped rails 19, such as Figure 4 The use of sleepers can increase the height of the track. Sleepers of corresponding height are laid according to the height of the top of the pile above the ground. When piles are driven to reinforce the riverbed to prevent landslides, there is basically no need to consider laying sleepers.

[0025] Figure 2 As can be seen in the figure, a bracket 4 is fixed to the base 2 of the frame 1. The bracket 4 is a cubic structure as a whole, which includes four columns, and crossbeams and connecting rods are fixed between adjacent columns. A stabilizing clamping mechanism 5 is fixed to the middle of the inner side of each of the four side walls of the bracket 4.

[0026] Figure 2 Combine Figure 8 Each stable clamping mechanism 5 includes a fixed seat 6, an outer pressure plate 7, an upper connecting plate 8 and a lower connecting plate 9. The ends of the upper connecting plate 8 and the lower connecting plate 9 are respectively hinged at the upper end of the fixed seat 6 and the lower end of the outer pressure plate 7. Figure 8 In order to always keep the height of the outer pressure plate 7 higher than the height of the fixing seat 6, it is best to connect a tension spring 10 at the upper pin position of the lower connecting plate and the lower pin position of the upper connecting plate. The tension spring can hold the outer pressure plate 7 upward and outward translation, that is, the outer pressure plate 7 is expanded outward in the natural state.

[0027] The four outer pressure plates 7 of the four sets of stabilizing clamping mechanisms 5 are combined to form the four sides of a quadrangular prism, equipped with a downward-pressing drive mechanism that drives the four outer pressure plates 7 downward. When the lower end of the pile is inserted into the inner side of the four outer pressure plates 7, the downward-pressing drive mechanism causes each inner pressure plate to press against the four sides of the pile. The side walls of the pile exert downward friction on each inner pressure plate. The further each inner pressure plate moves downward, the greater the clamping force. The weight of the pile and the mobile electric hammer at its upper end, combined with the pressure of each inner pressure plate, form a supporting relationship that prevents it from sliding downward. However, after the frame is moved into position, the downward-pressing drive mechanism releases the pressure on each inner pressure plate. Each inner pressure plate moves upward and outward under the action of the corresponding tension spring, causing the pile to fall to the ground. When the four inner pressure plates are extended outward a small distance, although their support for the pile is released, they still form a vertical channel, providing a guiding function for the pile and preventing it from tilting when impacted by the high-frequency electric hammer.

[0028] like Figure 1 and Figure 9 As shown, the C-shaped track 19 employed comprises a base and an upper C-shaped track groove. The C-shaped track groove comprises two side walls and a top notch, with shoulder plates flanking the notch. The inner track wheels are twin parallel wheels, each with a central axis. A shaft bracket is mounted on the central axis and secured to the bottom of the vehicle frame. The shaft bracket extends from the C-shaped track groove, but the twin parallel wheels of the inner track are located beneath the two shoulder plates. This track structure effectively constrains the vehicle frame, maintaining stability and, in particular, preventing it from tipping over.

[0029] During construction, this embodiment first utilizes the advantages of a crane, hoists a mobile electric hammer with a hook nearby, and carries the pile sinking to perform pile driving construction nearby. At the same time, the electric hammer carries the end fixed piles to the vertical channels on both sides of the end fixed frame at the starting position of the track, fixes the end fixed frame with the end fixed piles, fixes the ends of the C-shaped tracks on both sides with the end fixed frame, and fixes the middle and distal ends of the C-shaped track with anchor rods.

[0030] like Figure 7 The middle hook 29 is detached from the hook connection arc of the crane, and the lower end of the hook is fixed to the mobile electric hammer 30. The power cord of the mobile electric hammer comes from the crane or an external power supply. The bottom of the hook is connected to the clamp 31. The clamp 31 includes a fixed splint 1 32 and a fixed splint 2 34. A spacing adjustment plate 33 is sleeved on the inner side of the fixed splint 1 32 (parallel double screw holes are provided on the fixed splint 1 32 and are respectively installed on bolts, an adjusting nut is installed on the outer end of the bolt, and a spacing adjustment plate 33 is installed on the inner side of the bolt). An adaptive adjustment plate 35 is installed on the inner side of the fixed splint 2 34, and its upper and lower ends are hinged to the fixed splint 2 through a rocker to form a parallelogram. The upper side of the adaptive adjustment plate 35 is connected to a pull rope 37, and an electric-controlled pulling mechanism 36 is installed on the clamping body 31. The electric-controlled pulling mechanism 36 drives the pull rope 37 to move upward or release. When the pull rope moves upward in an arc, the adaptive adjustment plate is lifted upward and close to the fixed clamp plate 2. When the clamp is clamped with the upper end of the pile, the electric-controlled pulling mechanism releases the pull rope, causing the adaptive adjustment plate 35 to move inward and press against the upper end of the pile. When the lifting buckle moves upward, the pile presses the adaptive adjustment plate downward. The adaptive adjustment plate will press inward while moving downward, that is, the more it moves downward, the tighter it presses against the upper end of the pile, to ensure that it will not fall off during lifting.

[0031] When the carriage is moved to the starting point of the track, near the crane's auxiliary frame, the mobile electric hammer is used to clamp the pile. After lifting it, it is moved to the center of the four inner pressure plates above the carriage. Then, the downward drive mechanism is controlled to press each inner pressure plate against the lower end of the pile and fix it. Release the hook, but ensure that the power cord of the mobile electric hammer moves with the carriage to the far end. The equipment can be used to construct and guide the pile at any target location.

[0032] Example 2: A downward driving mechanism based on Example 1, such as Figure 2 and Figure 4 As shown, the downward drive mechanism includes a movable inner frame 11 and a swing frame assembly. The movable inner frame 11 comprises an upper inner frame transverse frame 12 consisting of four upper frames fixed end to end, and a lower inner frame transverse frame 13 consisting of four lower flat holes fixed end to end. A column connects the upper and lower inner frame transverse frames. Parallel limit plates 14 are connected to the middle of the upper and lower inner frame transverse frames. The upper and lower connecting plates of each stabilizing clamping mechanism are respectively inserted into the corresponding parallel limit plates 14.

[0033] The upper transverse frame 12 of the inner frame is located above the upper connecting plate 8 of each stable clamping mechanism 5 , and the lower transverse frame 13 of the inner frame is located below the lower connecting plate 9 of each stable clamping mechanism 5 .

[0034] A counterweight ring 15 is fixed below the lower horizontal frame 13 of the inner frame. Supports 16 are fixed on both sides of the base 2. L-shaped swing frames are hinged in the supports 16 on both sides. The L-shaped swing frame includes two parallel swing arms 17 and two parallel push rods 18. The two swing arms 17 are fixed together by a connecting rod and a handle 38. The two push rods 18 are supported below the two sides of the counterweight ring 15. Figure 4 As shown, when the handle 38 is pressed downward, the rocker arms 17 on both sides move downward, causing the top rods 18 on both sides to move upward, thereby driving the counterweight ring 15 to move upward. When the handle 38 is lifted upward, the top rods 18 on both sides move downward, thereby moving the counterweight ring 15 downward.

[0035] Since the upper transverse frame 12 of the inner frame is located above each upper connecting plate 8, when the handle 38 is lifted upward, the counterweight ring 15 moves downward, causing the upper transverse frame 12 of the inner frame to press each upper connecting plate 8 downward, thereby causing each outer pressure plate 7 to retract downward and inward. Since the lower transverse frame 13 of the inner frame is located below each lower connecting plate 9, when the handle 38 is pressed downward, the counterweight ring 15 moves upward, causing the upper transverse frame 12 of the inner frame to lose its pressure on the upper connecting plate 8. At this time, each outer pressure plate 7 is expanded upward and outward under the action of the tension spring 10, or is expanded upward and outward under the action of the lower transverse frame 13 of the inner frame lifting the lower connecting plate 9.

[0036] Based on the above structure, a bottom sleeve 46 can be further installed under each column and a locking wire can be installed. The bottom sleeve 46 and each column of the bracket are usually fixed together by the locking wire. When the sling needs to be lifted as a whole, the locking wires are loosened and the locking mechanism is used to lock each stable clamping mechanism 5. In this state, the handle is swung downward to lift the entire bracket upward.

[0037] Example 3: Based on Example 2, the swing frame assembly further includes a ground lock 39 located on the frame and a sky lock 40 located on the top of the bracket. Figure 2The ground lock 39 includes a base fixed on the frame, a vertical shaft is provided on the base, and a rotating plate is installed on the rotating shaft. When the handle 38 moves downward to the limit position, the rotating plate is rotated 90 degrees so that the rotating plate presses on the upper side of the handle to prevent the handle from automatically moving upward. Figure 2 As shown, the handle comprises a sliding sleeve that fits over the top crossbeam of the bracket. Two-stage slots are located on the outside of the sleeve. When the handle is moved upward to the upper side, the sleeve can be slid to engage the handle with either the first or second slot. The first slot is the limit slot. When the handle is in the first slot, the internal pressure plates lock the pile. When the handle is in the second slot, the internal pressure plates slightly expand outward to form a guide channel, but the internal pressure plates still effectively prevent the pile from tipping over.

[0038] Example 4: Based on the above examples 1-3, an absolute locking mechanism is used to stabilize the clamping mechanism 5. Figure 8 As shown, when the stabilizing clamping mechanism 5 is locked, the internal pressure plates can be locked by this mechanism. Figure 8 A vertical slide groove 41 is provided on the fixed seat 6, and a free slider 42 is installed in the vertical slide groove. The inner end of the free slider has a protruding limit top column 43, and the outer end of the free slider has a closed cavity, in which an inner pressure plate 45 is installed, and a top screw 44 is installed on the side wall. By screwing the top screw outward, the inner pressure plate loses its pressure on the fixed seat 6, and the free slider 42 can freely rise and fall and slide. However, after screwing the top screw inward, the inner pressure plate 45 is locked together with the fixed seat 6, so that the limit top column is supported on the upper side of the lower connecting plate 9, so that the lower connecting plate 9 cannot move upward, that is, the inner pressure plate cannot be expanded outward. The mechanism of this embodiment is mainly used for further locking effect after the pile is fixed. Compared with embodiment 1-3, embodiment 1-3 uses a counterweight ring to act on each inner pressure plate. This embodiment can achieve absolute locking of the inner pressure plate through a locking mechanism on this basis.

[0039] Example 5: Based on the above examples 1-3, the absolute locking function is realized by adopting a hydraulic drive method. Figure 5 and Figure 6As shown, locking mechanisms 21 are installed on the inner sides of the diagonal columns of the bracket 4. The locking mechanisms include a right-angle frame 22 at the top, an auxiliary frame 23 located outside the right-angle frame 22, and a sliding shaft 24 vertically connected to the lower middle part of the right-angle frame 22. A slide groove is fixed on the inner side of the bracket column, and the slide shaft is mounted in the slide groove and can be raised and lowered. A hydraulic cylinder 25 is connected to the base of the right-angle frame 22 and the lower side of the column of the bracket 4. By controlling the hydraulic cylinder to move up and down, it can drive each right-angle frame 22 to move up and down. Each right-angle frame 22 can compress the upper connecting plate 8 below it. When the pile is located inside each inner pressure plate, each right-angle frame presses down on each upper connecting plate, thereby making each inner pressure plate absolutely supported on the side of the pile. Compared with Example 4, Example 4 is passive locking, while this embodiment is active compression locking, which has the effect of further compressing the inner pressure plate.

[0040] Example 6: Based on the above examples 1-3, top screws are installed vertically in the middle of each upper frame of the movable inner frame 11. By adjusting the depth of each top screw, the upper connecting plate is driven to retract inward in turn, thereby being able to adapt to rectangular section piles or square section piles, and having the characteristic of alternating use of multiple piles.

[0041] Example 7: Based on the above embodiments, each outer pressure plate 7 can be further V-shaped or arc-shaped, or V-shaped or arc-shaped components can be installed on its surface to adapt to the cylindrical pile driving construction.

[0042] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and are not intended to limit the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
