Description

Technical Field

[0001] This utility model relates to the field of hoisting support technology, and more specifically, to a hoisting support for the production of rail transit components. Background Technology

[0002] Rail transit refers to a type of transportation vehicle or system in which operating vehicles need to run on specific tracks. The tracks are composed of components such as track bed, sleepers, and rails, and require the participation of hoisting equipment during their production or transportation.

[0003] Publication No. CN219906701U discloses a hoisting bracket for the production of rail transit components, belonging to the field of rail transit technology. It includes a crossbeam with support frames A and B symmetrically fixed on both sides. This utility model utilizes a hoisting mechanism where an electric cylinder extends to firmly clamp a fixing block onto both sides of the rail, securing one end of the rail. A winch with a torque motor drives the wire rope to wind up, completing the hoisting of the rail. No crane assistance is required; the hoisting can be completed autonomously, making it more convenient to use. A servo motor screw rotates, causing a slider to slowly move along the screw, dragging the rail above the conveyor trough. Then, the electric cylinder causes the fixing block to separate from the rail, and the rail falls onto the conveyor roller above the conveyor trough. The motor drives the conveyor roller to rotate, transporting the rail to the end of the conveyor trough until it enters the transport vehicle, completing the loading of the rail. No crane assistance is needed for loading and unloading, reducing operating costs.

[0004] However, this type of hoisting bracket for the production of rail transit components still has the following drawbacks: when the length of the hoisting track is long, the end of the track must not exceed the range of the conveying groove set on the right side of the connecting plate. This will cause the center of gravity of the track fixed by the electric cylinder and the fixing block to deviate, which will increase the actual hoisting operation of the track. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a hoisting bracket for the production of rail transit components, so as to solve the problem that when hoisting equipment hoists long rails, the rail ends cannot exceed the range due to the restriction of the right side conveying groove of the connecting plate, which easily leads to the deviation of the center of gravity and increases the hoisting danger.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a hoisting bracket for the production of rail transit components, comprising...

[0007] The support frame body has a winch body on its top. The outer surface of the middle part of the winch body is covered with a wire rope. An auxiliary traction mechanism is fixedly connected to the bottom end of the wire rope. An adjustable fastening component is fixedly connected to the bottom end of the auxiliary traction mechanism.

[0008] The adjustable fastening assembly includes a connecting plate and a clamping mechanism. An auxiliary traction mechanism is fixedly connected to the upper surface of the connecting plate. Extension frame plates are fixedly installed on both sides of the connecting plate in the width direction. A serrated plate is fixedly installed on the inner surface of the middle part of the bottom of the two extension frame plates, and a U-shaped block is slidably installed on the inner surface of each. A motor is fixedly installed on the side of the two U-shaped blocks that are far apart from each other, and the bottom surface of the two U-shaped blocks is slidably installed with the outer edge of the serrated plate. A gear is fixedly sleeved on the output end of each of the two motors. The two gears are rotatably installed in the middle of the two U-shaped blocks, and their outer surfaces mesh with the upper surface of the serrated plate. Two sets of clamping mechanisms are provided. The upper surfaces of the two sets of clamping mechanisms are fixedly installed with the lower surface of the connecting plate in the direction away from the connecting plate and fixedly installed with the bottom of the two U-shaped blocks, respectively.

[0009] The auxiliary traction mechanism includes a crossbar and lifting rings. The middle part of the crossbar is fixedly installed to the bottom end of the wire rope. Multiple lifting rings are provided on the upper surface of the connecting plate and the upper surface of the ends of the two extension frame plates. A traction rope is connected between the multiple lifting rings.

[0010] Both sets of clamping mechanisms include a crossbeam. The upper surfaces of the two crossbeams are fixedly installed on the lower surfaces of the connecting plates and the lower surfaces of the two U-shaped blocks, respectively. A second motor is fixedly installed on the side end of each crossbeam. A double-ended lead screw is fixedly sleeved at the output end of each second motor. The outer edges of the two ends and the middle of the double-ended lead screw are rotatably installed with the inner surface of the crossbeam. The outer surfaces of the two ends of the double-ended lead screw are threaded with fixing plates. The two fixing plates are symmetrically arranged, and the inner surface of the top end is slidably installed with the outer surface of the bottom of the crossbeam.

[0011] It also includes a base stabilization assembly, which has multiple sets on the side edge of the bottom of the support frame body.

[0012] The base stabilizing assembly includes a side plate and a snap-fit ​​mechanism. The side of the side plate is fixedly installed on the outer surface of the bottom of the support frame body. A movable rod is slidably sleeved on the inner surface of the side plate. A base plate is fixedly installed at the bottom end of the movable rod. A foot pad is detachably installed on the lower surface of the base plate. The snap-fit ​​mechanism is located in the middle of the side of the side plate away from the support frame body.

[0013] The locking mechanism includes a sleeve and a spring. The side end of the sleeve is fixedly installed to the side of the side plate. A movable column is slidably sleeved on the inner surface of the sleeve. An adjusting head is fixedly installed at one end of the movable column, and multiple protruding strips are fixedly installed on the outer surface of the other end. The end of the movable column with the protruding strips is slidably installed on the inner surface of the side plate and the movable rod. A circular plate is slidably sleeved on the inner surface of the sleeve. The middle part of the circular plate is fixedly sleeved on the outer surface of the movable column. One end of the spring is fixedly connected to the surface of the circular plate, and the other end is fixedly connected to the inner surface of the sleeve near the adjusting head.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above scheme, by setting up a winch body and adjustable fastening components, the device is moved to a suitable position during use. The wire rope is then loosened by the winch body, allowing the auxiliary traction mechanism and adjustable fastening components connected to the bottom of the wire rope to be lowered. The worker then assists in positioning the clamping mechanism at the bottom of the adjustable fastening components in the grooves in the middle of both sides of the rail. For hoisting longer rails, the worker first controls the gear connected to the output end of the motor to rotate in the middle of the U-shaped block and move it along the surface of the meshing sawtooth plate. This pulls the external U-shaped block and other structures to slide along the inner surface of the extension frame, causing the crossbeam installed at the bottom of the U-shaped block to move away from the connecting plate. The movement proceeds, and then the workers control the motors in the two clamping mechanisms to start. The two double-headed lead screws rotate inside the crossbeam, pulling the threaded fixing plates at both ends closer together, thus clamping them in the middle of the rail. Afterward, the winch body can be controlled again to wind up the wire rope, realizing the upward movement and hoisting of the auxiliary traction mechanism, adjustable fastening components, and clamped rail. By utilizing the above structure, the rail is clamped, and by adjusting the relative distance between the two clamping mechanisms, the stress on the rail can be distributed to a certain extent when hoisting longer rails, enhancing the stability of the hoisting operation and thus improving the safety and reliability of the operation.

[0016] In the above solution, by setting a base stabilizing component, after the device is moved to a suitable working position, the operator adjusts the locking mechanism to remove the limiting effect of the movable rod. Then, the movable rod is moved downward, and the groove at the top of the movable rod is aligned with the end of the locking mechanism. The locking mechanism is used to limit the movable rod. At this time, the foot pads installed on the lower surface of the base plate fixed at the bottom of the movable rod contact the ground, thereby providing further support for the device. This reduces the possibility of the device moving even with the self-locking rollers at the bottom of the support frame alone, and improves the stability and safety of the device.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a hoisting bracket for the production of rail transit components, including...

[0025] The support frame body 1 has a winch body 2 on top of it. The outer surface of the middle part of the winch body 2 is covered with a wire rope 3. The bottom end of the wire rope 3 is fixedly connected to an auxiliary traction mechanism 4. The bottom end of the auxiliary traction mechanism 4 is fixedly connected to an adjustable fastening component 5.

[0026] The adjustable fastening assembly 5 includes a connecting plate 50 and a clamping mechanism 56. An auxiliary traction mechanism 4 is fixedly connected to the upper surface of the connecting plate 50. Extension frame plates 51 are fixedly installed on both sides of the connecting plate 50 in the width direction. A serrated plate 52 is fixedly installed on the inner surface of the middle part of the bottom of the two extension frame plates 51, and a U-shaped block 53 is slidably installed on the inner surface of each. Motors 54 are fixedly installed on the sides of the two U-shaped blocks 53 that are far apart from each other. The bottom surfaces of the two U-shaped blocks 53 are slidably installed with the outer edge of the serrated plate 52. Gears 55 are fixedly sleeved on the output ends of the two motors 54. The two gears 55 are rotatably installed in the middle of the two U-shaped blocks 53, and their outer surfaces mesh with the upper surface of the serrated plate 52. Two sets of clamping mechanisms 56 are provided. The upper surfaces of the two sets of clamping mechanisms 56 are fixedly installed with the lower surface of the connecting plate 50 in the direction away from the side end of the connecting plate 50, and fixedly installed with the bottom of the two U-shaped blocks 53, respectively.

[0027] The auxiliary traction mechanism 4 includes a crossbar 40 and a lifting ring 41. The middle part of the crossbar 40 is fixedly installed with the bottom end of the wire rope 3. Multiple lifting rings 41 are provided on the upper surface of the connecting plate 50 and the upper surface of the ends of the two extension frame plates 51. A traction rope 42 is connected between the multiple lifting rings 41.

[0028] By setting up an auxiliary traction mechanism 4, the upper surface of the extension frame plate 51 away from the connecting plate 50, the upper surface of the connecting plate 50, and the multiple lifting rings 41 fixedly installed at the bottom of the crossbar 40 are connected by traction ropes 42, which further improves the stability of the connecting plate 50 and other structures in maintaining a horizontal position and reduces the phenomenon of tipping over.

[0029] Both sets of clamping mechanisms 56 include a crossbeam 560. The upper surfaces of the two crossbeams 560 are fixedly installed on the lower surfaces of the connecting plate 50 and the lower surfaces of the two U-shaped blocks 53, respectively. A second motor 561 is fixedly installed on the side end of each crossbeam 560. A double-ended lead screw 562 is fixedly sleeved at the output end of each motor 561. The outer edges of the two ends and the middle of the double-ended lead screw 562 are rotatably installed with the inner surface of the crossbeam 560. The outer surfaces of the two ends of the double-ended lead screw 562 are threadedly connected to fixing plates 563. The two fixing plates 563 are symmetrically arranged, and the inner surface of the top end is slidably installed with the outer surface of the bottom of the crossbeam 560.

[0030] It also includes a base stabilization component 6, which has multiple sets on the side edge of the bottom of the support frame body 1.

[0031] The base stabilizing component 6 includes a side plate 60 and a snap-fit ​​mechanism 64. The side of the side plate 60 is fixedly installed on the outer surface of the bottom of the support frame body 1. A movable rod 61 is slidably sleeved on the inner surface of the side plate 60. A base plate 62 is fixedly installed at the bottom end of the movable rod 61. A foot pad 63 is detachably installed on the lower surface of the base plate 62. The snap-fit ​​mechanism 64 is located in the middle of the side of the side plate 60 away from the support frame body 1.

[0032] By setting the base stabilizing component 6, after the device is moved to a suitable working position, the operator adjusts the locking mechanism 64 to remove the limiting effect of the movable rod 61. Then, the movable rod 61 is moved downward and the groove at the top of the movable rod 61 is aligned with the end of the locking mechanism 64. The locking mechanism 64 is used to limit the movable rod 61. At this time, the foot pad 63 installed on the lower surface of the base plate 62 fixedly installed at the bottom of the movable rod 61 contacts the ground, thereby providing further support for the device. This reduces the possibility of the device moving even with the self-locking rollers at the bottom of the support frame body 1, and improves the stability and safety of the device.

[0033] By setting foot pad 63, the top of foot pad 63 is detachably installed to the bottom of base plate 62 via a rotatable connecting rod and a top horizontal bar. First, rotate the horizontal bar to correspond to the horizontal groove opened inside base plate 62, then insert foot pad 63 upward into base plate 62, and finally rotate the horizontal bar to make it perpendicular to the horizontal groove of base plate 62, thereby completing the installation of foot pad 63 and improving the friction between base stabilizing component 6 and bottom.

[0034] The snap-fit ​​mechanism 64 includes a sleeve 640 and a spring 644. The side end of the sleeve 640 is fixedly installed with the side of the side plate 60. A movable column 641 is slidably sleeved on the inner surface of the sleeve 640. An adjusting head 642 is fixedly installed on one end of the movable column 641, and multiple protruding strips are fixedly installed on the outer surface of the other end. The end of the movable column 641 with the protruding strips is slidably installed with the inner surface of the side plate 60 and the movable rod 61. A circular piece 643 is slidably sleeved on the inner surface of the sleeve 640. The middle part of the circular piece 643 is fixedly sleeved with the outer surface of the movable column 641. One end of the spring 644 is fixedly connected to the surface of the circular piece 643, and the other end is fixedly connected to the inner surface of the end of the sleeve 640 near the adjusting head 642.

[0035] By setting up a locking mechanism 64, the operator moves the adjusting head 642 outward, and the movable column 641 connected to the adjusting head 642 slides laterally along the surface of the sleeve 640, the side plate 60, and the movable rod 61. The protruding strip installed at the end of the movable column 641 moves out from the inside of the movable rod 61, and the spring 644 inside the sleeve 640 is compressed. After the operator releases the force on the adjusting head 642, the spring 644 is elastically reset. The spring 644 drives the movable column 641 to move inward toward the movable rod 61 through the connected disc 643, so that the end of the movable column 641 is inserted into the inside of the movable rod 61, achieving the effect of limiting locking.

[0036] The working process of this utility model is as follows:

[0037] In use, the device is moved to a suitable position, and the wire rope 3 is loosened by the winch body 2, so that the auxiliary traction mechanism 4 and the adjustable fastening assembly 5 connected to the bottom end of the wire rope 3 are lowered. The operator then assists the clamping mechanism 56 at the bottom end of the adjustable fastening assembly 5 to be positioned in the grooves in the middle of both sides of the rail. For hoisting longer rails, the operator first controls the motor 54 to drive the gear 55 connected to the output end to rotate in the middle of the U-shaped block 53 and move it along the surface of the meshing sawtooth plate 52. This pulls the external U-shaped block 53 and other structures to slide along the inner surface of the extension frame plate 51, causing the crossbeam 560 installed at the bottom end of the U-shaped block 53 to move away from the connecting plate 50. Then… Workers control the motor 561 in the two clamping mechanisms 56 to start, and the two double-headed screws 562 rotate inside the crossbeam 560, pulling the fixed plates 563 with threaded connections at both ends closer together, thus clamping them in the middle of the rail. Afterwards, the winch body 2 can be controlled again to wind up the wire rope 3, realizing the upward movement and hoisting of the auxiliary traction mechanism 4, the adjustable fastening component 5, and the clamped rail. By using the above structure, the rail is clamped, and by adjusting the relative distance between the two clamping mechanisms 56, the stress on the rail can be distributed to a certain extent when hoisting a long rail, enhancing the stability of the hoisting operation and thus improving the safety and reliability of the operation.
