Description

Technical Field

[0001] This utility model relates to the field of hoisting tools, specifically a hoisting tool for laying subway tracks. Background Technology

[0002] Subways, as a convenient form of railway transportation, are becoming increasingly common in cities. Subway tracks consist of multiple interconnected rail sections, each primarily composed of two parallel steel rails and sleepers evenly arranged beneath them. During the laying of subway tracks, hoisting equipment is used to smoothly lift the rail sections to their designated positions.

[0003] However, existing rail hoisting tools require manual connection between the hoisting tool and the subway track during hoisting, which is cumbersome. In addition, the rails are prone to radial swaying during hoisting, which may lead to the safety hazard of the rail panel detaching from the hook. Therefore, we propose a hoisting tool for laying subway tracks. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a hoisting tool for laying subway tracks, which can reduce swaying during hoisting and can automatically connect with the rails to be hoisted, thereby improving hoisting efficiency and effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hoisting tool for laying subway tracks, comprising an installation frame and a clamping assembly;

[0006] Mounting frame: Two corresponding limiting frames are fixed at the left and right ends of the upper side. A leveling component is installed on the upper side of the mounting frame. Four corresponding fixing components are set at the left and right ends of the upper side of the mounting frame. A fastening component is installed at the lower end of the fixing component.

[0007] Clamping assembly: includes a fixed frame, a connecting rod, a first inclined block, an L-shaped extrusion strip, a first spring, and a second spring. Two corresponding fixed frames are fixed to the front and rear sides of the mounting frame. Two corresponding connecting holes are opened on the sides of the fixed frames. Four corresponding first inclined blocks are opened on the front and rear sides of the mounting frame. A connecting rod is fixed to the side of each first inclined block and slidably connected inside the connecting hole. An L-shaped extrusion strip is fixed to the end of the connecting rod away from the first inclined block. The four L-shaped extrusion strips are slidably connected inside the two limiting frames. A first spring is fixed to the side of each L-shaped extrusion strip, and the other end of the first spring is fixed to the side of the mounting frame. A second spring is sleeved on the circumference of the connecting rod. One end of the second spring is fixed to the side of the first inclined block, and the other end of the second spring is fixed to the side of the adjacent L-shaped extrusion strip. The four L-shaped extrusion strips are located above the four fixed components. The clamping assembly automatically clamps the subway track.

[0008] Furthermore, the fixing assembly includes directional holes, a second inclined block, a fixing frame, a slide rod, a connecting plate, and a third spring. Four corresponding directional holes are provided at the left and right ends of the upper side of the mounting frame. The second inclined block is slidably connected inside the directional holes. Four corresponding fixing frames are fixed inside the mounting frame. A slide rod is slidably connected inside each fixing frame. The slide rod is fixed to the lower side of the second inclined block. A connecting plate is fixed to the lower end of the slide rod. A third spring is sleeved on the circumference of the slide rod. The lower end of the third spring is fixed to the upper end of the connecting plate, and the upper end of the third spring is fixed to the lower side of the fixing frame. The L-shaped extrusion strip fits against the second inclined block. The fixing assembly further secures the subway track.

[0009] Furthermore, the fastening assembly includes a fastening disc and a fourth spring. The lower end of the connecting disc has a groove, and the fastening disc is slidably connected inside the groove. The upper end of the fastening disc is fixed with a fourth spring, which is fixed inside the groove. By setting the fastening assembly, the stability of the subway track can be ensured.

[0010] Furthermore, the leveling assembly includes a support frame, a T-shaped counterweight, a threaded rod, and a motor. The support frame is fixed to the upper side of the mounting frame, and the T-shaped counterweight is slidably connected inside the support frame. A threaded hole is opened on the right side of the T-shaped counterweight, and a threaded rod is threadedly connected inside the threaded hole. The threaded rod is rotatably connected inside the support frame. A motor is installed on the right side of the support frame, and the output shaft of the motor is fixed to the right end of the threaded rod. The input end of the motor is electrically connected to the output end of an external control switch. The mounting frame is leveled by setting up the leveling assembly.

[0011] Furthermore, two corresponding fixing strips are fixed at the left and right ends of the upper side of the mounting frame, and lifting rings are fixed on the upper side of the fixing strips, which are then connected to an external crane.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This hoisting tool for laying subway tracks has the following advantages:

[0013] By setting up an installation frame, when hoisting the subway track, the crane can control the installation frame to fall downwards over the subway track. At this time, under the weight of the installation frame itself, the subway track will squeeze the four first inclined blocks and move. Since the cross-section of the subway track is I-shaped, after the upper end of the subway track moves above the four first inclined blocks, the four first inclined blocks will return to their original positions under the action of all the first springs and all the second springs, thus locking into the grooves on both sides of the subway track. In this way, the subway track can be initially fixed, and the whole process is extremely convenient.

[0014] By setting up a fixing component, the subway track moves by squeezing the four first inclined blocks, which in turn causes the four L-shaped squeezing bars to move. The movement of the four L-shaped squeezing bars will squeeze the four second inclined blocks, causing the four connecting plates to move downwards. The downward movement of the four connecting plates will cause the four fastening plates to move downwards. When the four L-shaped squeezing bars are in place, the four fastening plates will be tightly attached to the upper side of the subway track under the action of the four third springs. After being attached, the subway track can be further fixed. In this way, the subway track can be prevented from slipping during hoisting.

[0015] By setting up a leveling component, the crane can observe the condition of the subway track when lifting it. When one side of the subway track tilts, the motor can be started to rotate the threaded rod. The rotation of the threaded rod causes the T-shaped counterweight to move in the opposite direction of the tilt of the subway track. In this way, the subway track can be balanced, avoiding tilting and thus preventing it from falling due to tilting. Attached Figure Description

[0023] Clamping assembly 3 includes a fixed frame 31, a connecting rod 32, a first inclined block 33, an L-shaped extrusion strip 34, a first spring 35, and a second spring 36. Two corresponding fixed frames 31 are fixed to the front and rear sides of the mounting frame 1. Two corresponding connecting holes are opened on the sides of the fixed frames 31. Four corresponding first inclined blocks 33 are opened on the front and rear sides of the mounting frame 1. A connecting rod 32 is fixed to the side of each first inclined block 33. The connecting rod 32 is slidably connected inside the connecting hole. An L-shaped extrusion strip 34 is fixed to the end of the connecting rod 32 away from the first inclined block 33.

[0025] The working principle of the hoisting tool for laying subway tracks provided by this utility model is as follows: First, a steel wire rope is connected to two lifting rings 8. After connection, the steel wire rope is connected to a crane. When hoisting the subway track, the crane can control the installation frame 1 to be positioned downwards over the subway track. At this time, under the weight of the installation frame 1, the subway track will be pressed against the four first inclined blocks 33 and moved. Since the cross-section of the subway track is I-shaped, when the upper end of the subway track moves above the four first inclined blocks 33, the four first inclined blocks 33 will return to their original position under the action of all the first springs 35 and all the second springs 36, thus engaging with the grooves on both sides of the subway track. In this way, the subway track can be initially fixed. During the process of the subway track pressing against the four first inclined blocks 33 and moving them, the subway track will... The four L-shaped pressing strips 34 move, which in turn presses the four second inclined blocks 42, causing the four connecting discs 45 to move downwards. The downward movement of the four connecting discs 45 causes the four fastening discs 51 to move downwards. When the four L-shaped pressing strips 34 are in place, the four fastening discs 51 will be tightly attached to the upper side of the subway track under the action of the four third springs 46. After attachment, the subway track can be fixed. In this way, the subway track can be prevented from sliding during hoisting. During hoisting, observe the condition of the subway track. When one side of the subway track tilts, the motor 64 can be started to rotate the threaded rod 63. The rotation of the threaded rod 63 causes the T-shaped counterweight 62 to move in the opposite direction of the tilt of the subway track. In this way, the subway track can be balanced and tilted, thus preventing it from falling due to tilting.
