Description

Technical Field

[0001] The utility model relates to a lifting device for lifting rails, in particular to a rail clamping device for lifting rails. Background Art

[0002] In the field of rail hoisting, the current method is to use two rail clamps cut from thick steel plates, then insert the rail clamps from both ends of the rail respectively, and then connect the two rail clamps with wire ropes, and finally use lifting equipment to lift the rails through the two rail clamps to achieve the lifting of the rails.

[0003] The current problem is that the existing rail lifting method has poor stability. The main reason is that the two rail clamps cannot really clamp the rails. As a result, the lifted rails are prone to the risk of tilting and sliding, posing a safety hazard to on-site workers. Summary of the invention

[0004] The utility model aims to provide a rail clamping device for rail hoisting, wherein two clamping plates in the rail clamping device can be combined to form a rail clamping configuration, thereby forming a stable and effective clamping posture for the rail to ensure that the rail will not slide or tilt during hoisting.

[0005] In order to achieve the above technical purpose, the utility model adopts the following technical solutions:

[0006] A rail clamping device for rail hoisting, the rail clamping device comprising a base plate and two clamping plates; the base plate is provided with a hoisting hole; the lower part of the clamping plate is arranged in a clamping claw configuration; the two clamping plates are rotatably mounted on the base plate through a rotating shaft connection mechanism, the rotation of the two clamping plates on the base plate can make the clamping claws of the two clamping plates approach or separate, when the clamping claws of the two clamping plates are close together, the two clamping plates can be combined to form a rail clamping configuration; a locking mechanism is arranged between the clamping plate and the base plate, when the two clamping plates are combined to form a rail clamping configuration, the locking mechanism can lock the clamping plate and the base plate together.

[0007] Furthermore, the locking mechanism provided between the clamping plate and the base plate is a pin hole positioning mechanism.

[0008] Furthermore, the pin hole positioning mechanism is specifically implemented in the form of a structure in which a positioning pin hole is provided on the base plate, a positioning pin hole is provided on the clamping plate, and a positioning pin is simultaneously inserted into the positioning pin hole of the base plate and the positioning pin hole of the rail, thereby forming the pin hole positioning mechanism.

[0009] Furthermore, the locking mechanism provided between the clamping plate and the base plate is a keyway locking mechanism.

[0010] Furthermore, the pivot connection mechanism is specifically implemented in the form of a structure in which a pivot hole is provided on the base plate, a pivot hole is provided on the clamping plate, and the pivot hole of the base plate is hingedly connected to the pivot hole of the clamping plate through an axle pin, thereby forming the pivot connection mechanism.

[0011] Compared with the prior art, the rail clamping device of the utility model has the following beneficial effects:

[0012] In the rail clamping device of the utility model, the rotation of the two clamping plates on the base plate can make the clamping claws of the two clamping plates approach or separate. When the clamping claws of the two clamping plates are close together, the two clamping plates can be combined to form a rail clamping configuration, and the locking mechanism is used to lock the rail clamping configuration. The rail clamping configuration can form a stable and effective clamping posture for the rail, so that the rail clamping device can firmly clamp the rail to ensure that the rail will not slide or tilt during lifting, thereby forming a safety guarantee for on-site workers. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the rail clamping device for rail hoisting of the utility model in a clamping state of the rail;

[0014] Figure 2 This is a schematic diagram of the rail clamping device of the utility model in a state of releasing the rail. DETAILED DESCRIPTION

[0015] The utility model is further described below with specific embodiments:

[0016] This embodiment provides a rail clamping device for lifting rails. The function of the rail clamping device is to form a stable and effective clamping posture for the rails to facilitate lifting of the rails.

[0017] See also Figure 1 and Figure 2 The rail clamping device of this embodiment includes a base plate 2 and two clamping plates 3.

[0018] The base plate 2 is in the shape of a plate as a whole, and a hoisting hole 21 is provided on the upper portion of the base plate 2. The hoisting hole 21 is used to cooperate with a hook of a hoisting device to achieve hoisting.

[0019] For the convenience of description, the parts on both sides of the lower part of the base plate 2 are referred to as clamping claw mounting parts, that is, two clamping claw mounting parts are symmetrically arranged at the lower part of the base plate 2.

[0020] Two through holes are provided at each jaw mounting portion as shaft pin holes, and the two jaw mounting portions are provided with a total of four shaft pin holes. For the convenience of description and based on the actual functions of the two shaft pin holes, the shaft pin hole at the upper side of the jaw mounting portion is called a "rotating shaft hole", and the shaft pin hole at the lower side of the jaw mounting portion is called a "positioning pin hole".

[0021] The configurations of the two clamping plates 3 are identical, and the two clamping plates 3 are arranged on the base plate 2 in a mirror-symmetrical manner.

[0022] Specifically,

[0023] For a single clamping plate 3, two through holes are provided on the upper portion of the clamping plate 3 as shaft pin holes. For the convenience of description and based on the actual functions of the two shaft pin holes, the shaft pin hole on the upper side of the clamping plate 3 is referred to as a "rotating shaft hole", and the shaft pin hole on the lower side of the clamping plate 3 is referred to as a "positioning pin hole".

[0024] In essence, the two clamping plates 3 correspond to the two clamping claw mounting parts of the base plate 2 respectively. As for a clamping plate 3 and a clamping claw mounting part corresponding to each other, the shaft hole of the clamping plate 3 corresponds to the shaft hole of the clamping claw mounting part, and the positioning pin hole of the clamping plate 3 corresponds to the positioning pin hole of the clamping claw mounting part.

[0025] In addition, the lower part of the clamping plate 3 is configured as a clamping claw configuration. When the clamping claws of the two clamping plates 3 are brought together to perform a gripping action, the two clamping plates 3 can be combined to form a rail clamping configuration, such as Figure 1 As shown, the rail 1 can be clamped.

[0026] The two clamping plates 3 are respectively mounted on the two clamping claw mounting portions of the base plate 2 .

[0027] Specifically,

[0028] At a clamping jaw installation portion, the rotation axis hole of the clamping plate 3 and the rotation axis hole in the clamping jaw installation portion are hingedly connected together through an axle pin. The axle pin hinge connection here is not disassembled.

[0029] The “axis holes are hinged together through axis pins” here actually constitutes a axis connection mechanism 32, that is, the clamping plate 3 is installed on the base plate 2 through the axis connection mechanism 32, so that the clamping plate 3 can rotate at the clamping claw mounting part of the base plate 2 based on the axis connection mechanism 32, and the rotation of the two clamping plates 3 on the base plate 2 can make the clamping claws of the two clamping plates 3 approach or separate.

[0030] The clamping jaws of the two clamping plates 3 are arranged opposite to each other. When the two clamping plates 3 are rotated until their clamping jaws are close together, the two clamping plates 3 can be combined to form a rail clamping configuration. At this time, the locating pin holes of the clamping plates 3 and the locating pin holes of the clamping jaw mounting portion just overlap with each other, that is, the locating pin holes of the two are aligned with each other, and an axial pin is used as a locating pin and inserted into the aligned locating pin holes mentioned above, so that "the clamping jaws of the two clamping plates 3 are close together, and the two clamping plates 3 are combined to form a rail clamping configuration" can be fixed.

[0031] The above-mentioned form of "locating pin inserted into the locating pin hole" is actually the pin hole positioning mechanism 31, that is, a pin hole positioning mechanism 31 is arranged between the clamping plate 3 and the substrate 2, and the pin hole positioning mechanism 31 can lock the clamping plate 3 and the substrate 2 together.

[0032] When the rail clamping device of this embodiment is used to hoist the rail 1, the positioning pin in the pin hole positioning mechanism 31 is first removed, and then the two clamping plates 3 are rotated so that the clamping claws of the two clamping plates 3 are separated (such as Figure 2 As shown), the rail 1 is then placed between the two clamping plates 3, and then the two clamping plates 3 are rotated again so that the clamping claws of the two clamping plates 3 are close together, and the two clamping plates 3 are combined to form a rail clamping configuration, thereby forming a clamping posture for the rail 1, and then the positioning pin is inserted into the pin hole positioning mechanism 31, so as to fix the clamping posture, that is, the rail clamping device clamps the rail 1 (as shown in FIG. Figure 1 As shown). The hook of the lifting equipment is hooked on the lifting hole 21 of the base plate 2, so that the rail 1 can be lifted and transported by the rail clamping device.

[0033] It should be noted that the pin hole positioning mechanism 31 provided between the clamping plate 3 and the base plate 2 mentioned above actually serves as a locking mechanism. In other embodiments, other forms of locking mechanisms may also be used, such as providing a keyway locking mechanism between the clamping plate 3 and the base plate 2, which can also achieve the function of the locking mechanism. The utility model has no particular limitation on the specific implementation form of the locking mechanism.

[0034] Based on the above detailed description of the rail clamping device of this embodiment, the rail clamping device of the utility model can be summarized as follows:

[0035] The rail clamping device of the utility model comprises a base plate 2 and two clamping plates 3;

[0036] A lifting hole 21 is provided on the upper portion of the base plate 2;

[0037] The lower part of each clamping plate 3 is configured as a clamping claw configuration;

[0038] The two clamping plates 3 are rotatably mounted on the base plate 2 via a rotating shaft connection mechanism 32. The rotation of the two clamping plates 3 on the base plate 2 can make the clamping claws of the two clamping plates 3 approach or separate. When the clamping claws of the two clamping plates 3 are close together, the two clamping plates 3 can be combined to form a rail clamping configuration. This rail clamping configuration can clamp the rail 1.

[0039] A locking mechanism is provided between each clamping plate 3 and the base plate 2. When the two clamping plates 3 are combined to form a rail clamping configuration, the locking mechanism can lock the clamping plate 3 and the base plate 2 together, thereby locking the rail clamping configuration, that is, locking the clamping posture of the rail 1, and finally enabling the rail clamping device to clamp the rail 1.

[0040] In the rail clamping device of this embodiment, the rotation of the two clamping plates 3 on the base plate 2 can make the clamping claws of the two clamping plates 3 approach or separate. When the clamping claws of the two clamping plates 3 are close together, the two clamping plates 3 can be combined to form a rail clamping configuration, which can form a stable and effective clamping posture for the rail 1, so that the rail clamping device can firmly clamp the rail 1 to ensure that the rail will not slide or tilt during hoisting, forming a safety guarantee for the on-site workers. In addition, the rail clamping device has a simple structure and is easy to use, which can greatly improve work efficiency and reduce labor intensity.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
