Description

Technical Field

[0001] The invention relates to the technical field of protective devices for water conservancy construction, and in particular to a supporting protective device for dam construction. Background Art

[0002] In water conservancy construction, bridge and dam maintenance operations are common tasks. These structures are often located in complex and difficult to directly reach locations, such as above the water, on steep slopes or high in the air. Therefore, the use of a hanging basket as a construction platform is particularly important in these maintenance operations. At present, the conventional structure of the hanging basket adopts a rectangular frame structure. When in use, it is lifted and moved to the place where construction is required by the hoisting structure. The hanging basket is prone to shaking during the movement, which not only affects the construction efficiency, but also increases the safety risk.

[0003] In the prior art, the patent document with the authorization announcement number CN213509527U discloses a safety protection hanging basket for water conservancy construction, including a box body and a first fixed plate, characterized in that the first fixed plate is fixedly connected to the outer wall of the box body, and the outer wall of the box body is respectively rotatably connected with a first connecting rod and a second connecting rod, and the first connecting rod and the second connecting rod are connected to the end away from the box body by rollers, and the first connecting rod and the second connecting rod are connected by a buffer assembly. When used specifically, by providing a first elastic member, a roller and a guide rod, when the device is running, the roller contacts the wall surface, and then drives the first connecting rod and the second connecting rod to rotate along the outer wall of the box body, so that the first elastic member has an opposite force on it, so that the device can be ensured to move smoothly along the wall surface, thereby improving the stability of the device when it is running. When the device is in use, for the vertical wall surface, it can provide lateral support so that the hanging basket can move stably, but the dam structure has a slope surface, and when it is used on the slope surface, it is not convenient to achieve stable side support movement. In addition, a suction cup is connected to the outer wall of the second fixed plate. During fixed-point construction, the side is adsorbed for stable support. However, for outdoor cement dams, the surface is not smooth enough, so it is not easy to fix them by suction cups. Summary of the invention

[0004] The present invention provides a supporting and protecting device for dam construction, so as to solve the technical problems in the prior art that the anti-skid hanging basket structure used in the construction of dams with slopes is unstable when moving and inconvenient to be fixed at a fixed point, which affects the construction efficiency and increases the safety risk.

[0005] In order to solve the above problems, the present invention provides a support and protection device for dam construction adopts the following technical solution:

[0006] It includes a protective hanging basket body, one side of which is hingedly provided with an inclined support plate with an adaptive slope, the inclined support plate is provided with a reinforcement for fitting with and grasping the slope, the side of the inclined support plate away from the protective hanging basket body is provided with a moving wheel, and the protective hanging basket body is provided with an adaptive adjustment mechanism for adjusting the inclination angle of the inclined support plate according to the slope.

[0007] The adaptive adjustment mechanism includes a movable guide rail vertically arranged on the side of the protective hanging basket body and opposite to the inclined support plate, the movable guide rail is vertically provided with a movable guide groove, a movable pin is horizontally penetrated in the movable guide groove, one end of the movable pin is hinged to the side of the inclined support plate and the other end is provided with a limit plate, a composite spring sleeved on the movable pin is provided between the side of the movable guide rail away from the inclined support plate and the limit plate, the end of the composite spring away from the limit plate is provided with a movable ring sleeved on the movable pin, the movable ring is relative locked or unlocked with the movable pin by rotation, and when the inclined support plate adaptively fits the slope, the movable ring moves on the movable pin, and the movable pin moves in the movable guide groove at the same time.

[0008] With the above technical solution, the inclined support plate can be adaptively adjusted according to the angle of the dam slope to ensure that it remains parallel or nearly parallel to the dam slope. This stable support can reduce the shaking of the hanging basket on the slope and provide a more stable working platform for construction workers. It can also perform continuous operations on dams with different slopes without frequent changes of position or adjustments of posture, thus improving construction efficiency.

[0009] In addition, the adaptive adjustment mechanism can make the inclined support plate more stable during adaptive adjustment, and on the other hand, the adaptive adjustment mechanism can provide a certain shock-absorbing effect when the inclined support plate moves, so that the inclined support plate is more stable during support movement.

[0010] Furthermore, a limiting groove is provided on the surface of the movable pin, and the limiting groove is provided between the limiting plate and the movable guide rail, and a convex shaft extending into the limiting groove is provided on the inner wall of the movable ring.

[0011] The limiting groove comprises a moving groove distributed along the axial direction of the moving pin, and a locking groove is arranged at one end of the moving groove close to the moving guide rail, and the locking groove is perpendicular to the moving groove.

[0012] Furthermore, when the convex shaft on the movable ring is in the locking groove, the side surface of the movable ring abuts against the side surface of the movable guide rail, and a steel ball for abutting against the side surface of the movable guide rail is provided on the side surface of the movable ring.

[0013] By adopting the above technical solution, the stable locking and flexible movement of the moving ring on the moving pin are achieved through an ingenious mechanical structure, while friction and jamming are reduced, thereby improving the convenience of operation and the durability of the overall structure.

[0014] Furthermore, a telescopic component cooperating with the moving pin is provided at the bottom end of the movable guide groove, the top end of the telescopic component abuts against the moving pin and a guide roller is rotatably provided at the top end, and the axial direction of the guide roller is perpendicular to the axial direction of the moving pin.

[0015] Furthermore, the telescopic assembly comprises a guide cylinder fixedly arranged at the bottom end of the movable guide groove, a movable rod is slidably arranged in the guide cylinder, and a shock-absorbing spring column is arranged at the bottom end of the movable rod.

[0016] With the above technical solution, the telescopic assembly provides additional support and buffering for the vertical movement of the moving pin through the shock-absorbing spring column inside it. When the moving pin moves vertically downward in the moving guide groove, the shock-absorbing spring column can absorb and disperse the impact force generated during the movement, thereby enhancing the stability of the inclined support plate when adjusting the angle on the adaptive slope. Among them, the guide roller reduces the friction resistance between the moving pin and the telescopic assembly, making the angle adjustment process of the inclined support plate smoother and more efficient.

[0017] In addition, the telescopic assembly can also work together with the composite spring to further improve the stability of the inclined support plate moving on the slope. When the inclined support plate moves on the slope, the combined action of the composite spring and the shock-absorbing spring column can absorb and disperse the vibration and impact force from the slope, so that the inclined support plate can fit the slope more stably.

[0018] Furthermore, a notch is provided on the inclined support plate, and the reinforcement member includes a reinforcing plate arranged in the notch, and conical anti-slip pins are arrayed on the outer surface of the reinforcing plate, and a connecting plate is hinged at the bottom end of the reinforcing plate, and an avoidance groove is provided at the bottom end of the notch, and the connecting plate is hinged in the avoidance groove.

[0019] Furthermore, a slot hole vertically penetrating the inclined support plate is provided at the top of the slot, a steel wire rope for pulling the reinforcement plate is connected to the top of the reinforcement plate, and a winch assembly for winding or releasing the steel wire rope is provided on the inner wall of the protective hanging basket body.

[0020] Furthermore, the hoisting assembly includes an auxiliary plate arranged on the inner wall of the protective hanging basket body and a reel rotatably supported by the auxiliary plate, wherein a threaded pin for locking the reel is provided on one of the auxiliary plates, and a handwheel is provided at one end of the reel.

[0021] With the above technical solution, after the protective hanging basket body is moved to the location where construction is required through the hoisting structure, the reinforcement plate is lowered. The setting of the reinforcement plate significantly enhances the contact area and gripping force between the inclined support plate and the slope surface. Through the conical anti-skid pins arranged in an array, the reinforcement plate can more effectively fit the slope surface, provide additional friction and stability, and prevent the protective hanging basket body from shaking, sliding or tilting during construction.

[0022] Furthermore, a carrier plate with adjustable angle is hinged near the bottom end of the protective hanging basket body, an auxiliary frame is provided on the bottom surface of the protective hanging basket body, a telescopic member is hinged on the auxiliary frame, and the free end of the telescopic member is hinged to the bottom surface of the carrier plate.

[0023] Furthermore, a shock-absorbing member is provided on the outer surface of one side of the protective hanging basket body close to the inclined support plate.

[0024] By adopting the above technical solution, when the protective hanging basket body needs to be tilted during construction, the carrier plate can be dynamically adjusted through the action of the telescopic parts so that the carrier plate is in a horizontal state, so that the workers always stand on the flat plate, thereby improving stability and safety during the operation.

[0025] The beneficial effects of the support and protection device for dam construction provided by the present invention are as follows: when in use, the present invention provides reliable support for the movement of the protective hanging basket body through the inclined support plate that can adaptively adjust the angle, reduces the sliding of the protective hanging basket body during movement, and enhances the safety during operation. The reinforcing plate that is retractably hingedly connected to the inclined support plate increases the contact area and friction with the slope surface through structures such as anti-slip pins, ensuring that the inclined support plate is firmly attached to the slope surface. In addition, the carrier plate is arranged at a position near the bottom end of the protective hanging basket body, and its angle is dynamically adjusted through the action of the telescopic member to maintain a horizontal state, thereby improving the stability and safety of the operation.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0038] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0039] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0040] Embodiments of the supporting and protecting device for dam construction provided by the present invention:

[0041] like Figures 1 to 8 As shown, it includes a protective hanging basket body 1, wherein the top four corners of the protective hanging basket body 1 are provided with lifting rings. One side of the protective hanging basket body 1 is hingedly provided with an inclined support plate 2 with an adaptive slope. The side of the inclined support plate 2 away from the protective hanging basket body 1 is provided with a moving wheel 21, wherein the moving wheel 21 is specifically a universal wheel for more flexible movement. The protective hanging basket body 1 is provided with an adaptive adjustment mechanism 4 for adjusting the inclination angle of the inclined support plate 2 according to the slope.

[0042] In this embodiment, the adaptive adjustment mechanism 4 includes a movable guide rail 41 vertically arranged on the side of the protective hanging basket body 1 and opposite to the inclined support plate 2, a movable guide groove 42 is vertically arranged on the movable guide rail 41, a movable pin 43 is horizontally penetrated in the movable guide groove 42, one end of the movable pin 43 is hinged to the side of the inclined support plate 2 and the other end is provided with a limit plate 44, a composite spring 45 is provided between the side of the movable guide rail 41 away from the inclined support plate 2 and the limit plate 44 and is sleeved on the movable pin 43, a movable ring 46 is provided on the end of the composite spring 45 away from the limit plate 44 and is sleeved on the movable pin 43, the movable ring 46 is rotated to achieve relative locking or unlocking with the movable pin 43, when the inclined support plate 2 adaptively fits the slope, the movable ring 46 moves on the movable pin 43, and the movable pin 43 moves in the movable guide groove 42 at the same time.

[0043] When the moving ring 46 is in a locked state, the angle between the side surface close to the inclined support plate 2 and the inclined support plate 2 is less than 5°.

[0044] When the protective hanging basket body 1 is hoisted to the side of the dam with a slope by the hoisting mechanism, the moving wheel 21 at the bottom of the inclined support plate 2 first contacts the side of the dam because the protective hanging basket body 1 is in a vertical state. When the moving ring 46 rotates to achieve the unlocked state, the moving ring 46 can slide on the moving pin 43. Due to the gravity of the inclined support plate 2 itself, the hinged inclined support plate 2 will tilt and fall down toward the slope of the dam until the moving wheel 21 on the upper side of the inclined support plate 2 contacts the side of the dam. In this process, the moving ring 46 gradually moves away from the moving guide rail 41, and at the same time, the moving pin 43 gradually moves downward in the moving guide groove 42, cooperating to realize the adaptive angle adjustment of the inclined support plate 2, so as to realize that the inclined support plate 2 is parallel to the slope of the dam.

[0045] When the moving ring 46 gradually moves in a direction away from the moving guide rail 41 , the composite spring 45 is gradually compressed. Through the action of the composite spring 45 , the stability of the self-adaptive adjustment angle of the inclined support plate 2 is improved.

[0046] In addition, when the moving wheel 21 is moving, when the dam slope is uneven, the composite spring 45 cooperates with the moving pin 43, the moving ring 46 and the limit plate 44 to achieve a certain shock absorption effect, thereby improving the moving stability of the moving wheel 21 on the dam slope.

[0047] In this embodiment, a limiting groove 431 is provided on the surface of the movable pin 43 , and the limiting groove 431 is provided between the limiting plate 44 and the movable guide rail 41 . A convex shaft 461 extending into the limiting groove 431 is provided on the inner wall of the movable ring 46 .

[0048] The limiting groove 431 includes a moving groove 4311 distributed along the axial direction of the moving pin 43 . An end of the moving groove 4311 close to the moving guide rail 41 is provided with a locking groove 4312 , and the locking groove 4312 is perpendicular to the moving groove 4311 .

[0049] Under normal conditions, the convex shaft 461 on the movable ring 46 is in the locking groove 4312. At this time, the position of the movable ring 46 is locked and cannot move on the movable pin 43. When external force acts on the movable ring 46, that is, the movable ring 46 is rotated so that the convex shaft 461 is in the movable groove 4311, the movable ring 46 can move on the movable pin 43.

[0050] When the protruding shaft 461 on the moving ring 46 is in the locking groove 4312 , the side surface of the moving ring 46 abuts against the side surface of the moving guide rail 41 , and a steel ball 462 is provided on the side surface of the moving ring 46 for abutting against the side surface of the moving guide rail 41 .

[0051] When the convex shaft 461 is in the locking groove 4312, the composite spring 45 is in a slightly compressed state, so that the side of the moving ring 46 abuts against the side of the moving guide rail 41, and the moving ring 46 is clamped between the composite spring 45 and the moving guide rail 41 to maintain a stable locking state. The side of the moving guide rail 41 can provide a side support force when the moving ring 46 rotates, making it easier to act on the moving ring 46 to rotate.

[0052] In addition, when the movable pin 43 moves in the movable guide groove 42, the steel ball 462 contacts the side of the movable guide rail 41 to provide rolling friction, thereby preventing the movable pin 43 from getting stuck when moving.

[0053] In this embodiment, a telescopic component 47 cooperating with the moving pin 43 is provided at the bottom end of the movable guide groove 42. The top end of the telescopic component 47 abuts against the moving pin 43 and a guide roller 471 is rotatably provided at the top end. The axial direction of the guide roller 471 is perpendicular to the axial direction of the moving pin 43.

[0054] The telescopic assembly 47 includes a guide cylinder 472 fixed at the bottom end of the movable guide groove 42 , a movable rod 473 is slidably arranged in the guide cylinder 472 , and a shock-absorbing spring column is arranged at the bottom end of the movable rod 473 .

[0055] When the moving pin 43 moves vertically downward in the moving guide groove 42, it pushes the moving rod 473 downward, and the moving rod 473 gradually compresses the shock-absorbing spring column, so that the vertical movement of the moving pin 43 is more stable through the action of the shock-absorbing spring column. That is, the inclined support plate 2 is more stable when the angle is adjusted on the adaptive slope.

[0056] In addition, the telescopic assembly 47 can cooperate with the composite spring 45 to help improve the stability of the inclined support plate 2 moving on the slope.

[0057] It should be noted that when the movable pin 43 moves vertically in the movable guide groove 42, the movable pin 43 will produce an axial movement relative to the movable rod 473. The guide roller 471 can reduce the friction between the movable pin 43 and the movable rod 473, thereby improving the stability of the overall structure.

[0058] In this embodiment, a slot 22 is provided on the inclined support plate 2, and the reinforcement member 3 includes a reinforcing plate 31 arranged in the slot 22, and an array of conical anti-slip pins 311 are provided on the outer surface of the reinforcing plate 31. The bottom end of the reinforcing plate 31 is hinged with a connecting plate 32, and the bottom end of the slot 22 is provided with an avoidance groove 221, and the connecting plate 32 is hinged in the avoidance groove 221.

[0059] Both ends of the connection plate 32 are hinged, so that the reinforcement plate 31 can be adaptively parallel to the slope surface. Then the anti-slip pin 311 contacts the slope surface to provide a gripping force, thereby improving the static stability of the protective hanging basket body 1 during the construction process.

[0060] That is, after the protective hanging basket body 1 is moved to the location where construction is required by the hoisting structure, the reinforcing plate 31 is lowered. The setting of the reinforcing plate 31 significantly enhances the contact area and gripping force between the inclined support plate 2 and the slope surface. Through the tapered anti-slip pins 311 arranged in an array, the reinforcing plate 31 can more effectively fit the slope surface, provide additional friction and stability, and prevent the protective hanging basket body 1 from shaking, sliding or tilting during construction.

[0061] The top of the notch 22 is provided with a slot hole 23 vertically penetrating the inclined support plate 2, the top of the reinforcement plate 31 is connected with a steel wire rope 33 for pulling the reinforcement plate 31, and the inner wall of the protective hanging basket body 1 is provided with a hoisting assembly 11 for winding or releasing the steel wire rope 33. The steel wire rope 33 passes through the slot hole 23 and is connected to the hoisting assembly 11.

[0062] Among them, the winch assembly 11 includes an auxiliary plate 111 arranged on the inner wall of the protective hanging basket body 1 and a reel 112 rotatably supported by the auxiliary plate 111, one of the auxiliary plates 111 is provided with a threaded pin 113 for locking the reel 112, and a handwheel is provided at one end of the reel 112.

[0063] It should be noted that when the reinforcing plate 31 is in the notch 22 by the traction and fixing action of the steel wire rope 33, there is a gap between the reinforcing plate 31 and the slope surface, so as to avoid the interference of the reinforcing plate 31 with the movement of the reinforcing plate 31 when the inclined support of the inclined support plate 2 assists the movement of the protective hanging basket body 1.

[0064] When the reinforcing plate 31 needs to be lowered after moving into position, the threaded pin 113 is loosened, and then the hand wheel is driven to release the wire rope 33 to realize the lowering of the reinforcing plate 31. On the contrary, when it needs to be put away, the hand wheel is rotated in the opposite direction.

[0065] In this embodiment, a carrier plate 12 with an adjustable angle is hinged near the bottom end of the protective hanging basket body 1, and an auxiliary frame 13 is provided on the bottom surface of the protective hanging basket body 1. A telescopic member 14 is hinged on the auxiliary frame 13, and the free end of the telescopic member 14 is hinged to the bottom surface of the carrier plate 12. The telescopic member 14 is specifically a cylinder. One end of the carrier plate 12 close to the inclined support plate 2 is hinged to the inner wall of the protective hanging basket body 1, and the other end is supported by the telescopic member 14, so that the angle of the carrier plate 12 can be adjusted easily.

[0066] During the specific construction process, in order to meet the needs of the staff, sometimes the staff needs to operate close to the slope. At this time, the staff moves to the side of the protective hanging basket body 1 close to the slope and leans against the side. At this time, the protective hanging basket body 1 will have a certain inclination, that is, the protective hanging basket body 1 is inclined close to the inclined support plate 2. At this time, the protective hanging basket body 1 itself is in an inclined state. At this time, the carrier plate 12 can be dynamically adjusted through the action of the telescopic member 14, so that the staff always stands on the flat plate, improving the stability and safety during the operation.

[0067] The outer surface of the protective hanging basket body 1 close to the inclined support plate 2 is provided with a shock absorbing member 15. The shock absorbing member 15 includes a sleeve 151 and a shock absorbing rod 152 slidably arranged in the sleeve 151, a spring column is arranged at the bottom end of the shock absorbing rod 152, and a rubber pad is arranged at the free end of the shock absorbing rod 152.

[0068] Under normal conditions, when the inclined support plate 2 is in the initial state, the shock absorbing spring column is in a compressed state. Under the rotating state, when the protective hanging basket body 1 is tilted close to the inclined support plate 2, the shock absorbing member 15 is used to improve the contact stability.

[0069] When the supporting and protecting device for dam construction of this embodiment is used, the protective hanging basket body 1 is lifted by the hoisting structure, and after reaching one side of the dam slope, the inclined support plate 2 is lowered by the adaptive adjustment mechanism 4, and the inclined support plate 2 is adaptively adjusted to fit the slope, and the inclined support plate 2 can provide side support, and then the protective hanging basket body 1 is moved to the specific location where construction is required by traction of the hoisting structure. After arriving at the specific location, the reinforcement plate 31 is lowered so that the reinforcement plate 31 can fit the slope more effectively, provide additional friction and stability, and prevent the protective hanging basket body 1 from shaking, sliding or tilting during the construction process.

[0070] In addition, during the specific construction process, when the construction workers move to the side close to the slope, the protective hanging basket body 1 itself is in an inclined state. At this time, the carrier plate 12 can be dynamically adjusted through the action of the telescopic part 14, so that the workers always stand on the flat board, thereby improving the stability and safety of the operation process.
