Description

Technical Field

[0001] The utility model relates to the technical field of clampers, in particular to an I-shaped rail clamp with adjustable height. Background Art

[0002] At present, in industrial plants, rail clamps are generally used for pipeline lifting. Therefore, the stability of the rail clamp is crucial to the stability during the lifting process. During the use of the current rail clamps, the heavy objects being lifted will produce a certain degree of swaying during the lifting process, which will cause the rail clamps to sway left and right and tilt on the I-beam, thereby causing the lifted objects to vibrate in the air, making the lifting process present a greater risk factor.

[0003] The prior art includes a utility model with publication number CN218909586U, which discloses a rail clamp. The patent adopts two clamps with the same structure, a pin connecting the two clamps and an adjusting screw passing through the two clamps respectively. The two clamps are arranged opposite to each other, and each clamp includes a hook part, a main body part and a connecting part which are connected in sequence. The hook part is suspended and supported on the steel beam, and the pin passes through the two connecting parts respectively to make the two clamps rotate relative to each other. The adjusting screw passes through the two main bodies respectively to fix the two clamps. There is a groove between the hook part and the main body part; an elastic part is located in the groove; there are two abutting parts, and the two abutting parts are connected to the hook part respectively. When the two hook parts clamp the steel beam, the abutting parts also abut against the "I"-shaped groove of the steel beam. The problem that the conventional rail clamp will shake on the I-beam during use, causing the suspended objects to vibrate in the air, which is highly dangerous, is solved.

[0004] The inventors have found in their daily work that when transporting I-shaped rails, due to the large weight of the workpiece, when construction workers use clamps to transport the workpiece, there is a problem that the equipment is difficult to clamp firmly when mechanically clamping the larger I-shaped rail, making the equipment difficult to use. Utility Model Content

[0005] The utility model aims to solve the shortcoming in the prior art that it is difficult for equipment to clamp workpieces of different models, and proposes an I-shaped rail clamp with adjustable height.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a height-adjustable I-beam rail clamp, comprising a first clamp and a stretching device, a second clamp is arranged on one side of the first clamp, a connector is arranged at the connecting end of the first clamp and the second clamp, a rotating nut is rotatably connected inside the second clamp, the internal thread of the rotating thread is connected to a threaded rod, one end of the threaded rod is rotatably connected to the inner wall of the first clamp, the stretching device is arranged inside the connector, the stretching device comprises a first connecting block and a second connecting block, one end of the first connecting block is fixedly connected to a connecting plate, the connecting plate is slidably connected to the inner wall of the second connecting block, the end of the connecting plate away from the first connecting block is fixedly connected to a limiting block, and two equidistant limiting holes are provided on the surface of the connecting plate.

[0007] Preferably, a limiting rod is fixedly connected to the surface of the second connecting block, and a pull plate is slidably connected to the inner wall of the limiting rod. The pull plate can be limited by fixing the limiting rod on the surface of the second connecting block, thereby reducing the possibility of the pull plate shaking when the device is in use.

[0008] Preferably, one end of the pull plate is fixedly connected to a stabilizing rod, and the stabilizing rod is engaged with the inner wall of the limiting hole. The stabilizing rod is provided to facilitate limiting the connecting plate.

[0009] Preferably, a first spring is fixedly connected to the surface of the pull plate, one end of the first spring away from the pull plate is fixedly connected to one end of the limit rod, and a pull handle is fixedly connected to the surface of the pull plate, and the pull handle is provided to facilitate manual movement of the pull plate.

[0010] Preferably, a stabilizing device is fixedly connected to the lower surfaces of the first clamping plate and the second clamping plate, and the stabilizing device includes a convex plate and a positioning plate, the convex plate is fixedly connected to the lower surfaces of the first clamping plate and the second clamping plate, the positioning plate is fixedly connected to the surface of the convex plate, and a sliding rod is slidably connected to the inside of the positioning plate. By fixing the positioning plate on the surface of the convex plate, the direction of the positioning block can be restricted, thereby reducing the possibility of the positioning block being easily displaced when the equipment is in use.

[0011] Preferably, one end of the slide rod is fixedly connected to a positioning block, and one end of the slide rod away from the positioning block is fixedly connected to a pull rod. The slide rod is provided to facilitate the movement of the positioning block.

[0012] Preferably, a second spring is fixedly connected to the surface of the pull rod, and one end of the second spring away from the pull rod is fixedly connected to the surface of the positioning block. The second spring is provided to facilitate applying elastic force to the positioning block.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when the I-shaped rail is being transported, since the workpiece is too heavy, the construction workers use a clamp to transport the workpiece. When using the equipment, the user pulls the pull handle, and the movement of the pull handle drives the pull plate to move. When the pull plate moves, it drives the stabilizing rod to move. The movement of the stabilizing rod drives the first spring to displace and deform to generate elastic force. When the stabilizing rod moves out of the limiting hole, the connecting plate moves to lengthen the length of the first clamping plate and the second clamping plate, and then the restraint on the pull handle is released. The first spring resets and drives the stabilizing rod to engage with the inside of the limiting hole. By setting up a stretching device, the equipment is effectively stretched, which plays a role in clamping the first clamping plate and the second clamping plate, reducing the situation that the equipment is difficult to clamp stably when the equipment mechanically clamps the larger I-shaped rail when in use, causing difficulty in using the equipment, thereby improving the practicability of the equipment.

[0015] 2. In the utility model, by providing a stabilizing device, when the equipment is used, when the user combines the equipment with the surface of the I-shaped rail, the user pulls the pull rod to move, which drives the sliding rod to move, and the sliding rod moves to drive the positioning block to move, and the positioning block moves to drive the second spring to deform and generate elastic force. When the equipment is combined with the I-shaped rail, the restraint on the pull rod is released, and the second spring resets to drive the positioning block to be firmly combined with the surface of the I-shaped rail. By providing a stabilizing device, the equipment and the material are effectively stabilized, which plays a role in preventing the equipment from slipping, reduces the risk of the equipment sliding on the surface of the workpiece when the equipment is used in combination with the surface of the I-shaped rail, and causes the equipment to detach from the workpiece and the workpiece to fall off, thereby improving the practicability of the equipment.

[0026] In this embodiment, by fixing the limiting rod 67 on the surface of the second connecting block 62, the pull plate 66 can be limited, thereby reducing the possibility of the pull plate 66 shaking when the device is in use.
