[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] See also Figure 1 、 2 As shown;

[0040] The utility model discloses a lifting device for installing a special-shaped handrail bracket of a rail vehicle, comprising:

[0041] A base 1, a support rod and at least one clamp 6;

[0042] The support rod is fixedly connected to the base 1 and extends upward, and the clamp 6 is fixedly connected to the connecting seat 5 provided at the top end of the support rod. When in use, the clamp 6 is supported by the support rod so that the clamp 6 is at the height of the support armrest bracket;

[0043] The upper portion of the clamp 6 is formed with a clamping area A perpendicular to the axis of the support rod for supporting and clamping the armrest bracket. The clamp 6 is movably connected to two clamping claws 602 in the clamping area A. When in use, the clamping claws 602 are used to position the armrest bracket in the clamping area A, thereby lifting and holding the armrest bracket without external force. When the clamp 6 moves away from the armrest bracket and is in the process of moving away, the clamping claws 602 rotate to release the armrest bracket, separating the lifting device from the armrest bracket. When not in use, the two clamping claws 602 on the clamp 6 are in an open state.

[0044] The clamp 6 provided in the lifting device of the structure has a vertical support rod. When the clamp 6 is in the vertical state, the clamp claw 602 of the clamp 6 automatically generates an inward locking action of the handrail bracket under the downward pressure of the handrail bracket, and automatically releases the handrail bracket otherwise. It does not require manual adjustment or external force, and is automatically adjusted. At the same time, the clamp can match handrail brackets of different pipe diameters within a certain specification range.

[0045] See also Figure 5-8 As shown, preferably, the clamp 6 includes a support 601, and upwardly extending ear plates are arranged at intervals on the upper surface of the support 601, and the ear plates are provided with grooves with a concave arc structure for forming a clamping area A. The ear plates are located on both sides of the clamping area A and are symmetrically hinged with clamping claws 602 through a horizontal axis 603, and the clamping claws 602 are located on one side of the horizontal axis 603 to form a first claw body 6021 that embraces the armrest bracket, and on the other side to form a second claw body 6022 that embraces the armrest bracket and can extend into the bottom of the armrest bracket.

[0046] Specifically, in this structure, the support 601 is the main body of the clamp 6, and a threaded hole is provided at the bottom of the support 601 for threaded connection with the connecting seat 5. The upper part of the support 601 forms a support clamping area A of a concave arc structure through two vertically arranged ear plates. The horizontal axis 603 can be a bolt in the prior art or a pin. This embodiment takes a hexagonal bolt as an example. The bolt passes through the two ear plates horizontally, and the mounting hole provided in one ear plate is a threaded hole. The bolt is located in the middle position of the two ear plates to hinge the clamping jaws 602, so that the two clamping jaws 602 embrace the handrail bracket from both sides in the support clamping area A. The clamping jaw 602 is constructed as an arc structure, preferably an arc structure not larger than half a circle. The clamping jaw 602 is provided with an axial hole connected to the horizontal axis 603. The clamping jaw 602 is displaced on one side of the axial hole to form a first claw body 6021, and on the other side A second claw body 6022 is formed, and the second claw body 6022 is located at the bottom of the armrest bracket. The length of the second claw body 6022 is smaller than the length of the first claw body 6021. The first claw body 6021 and the second claw body 6022 are affected by their own gravity, and the clamping jaws 602 rotate around the horizontal axis 603. The top ends of the two relatively arranged clamping jaws 602 are away from the center position of the clamping area A, that is, the two clamping jaws 602 are in an open state. When in use, after the armrest bracket is in place and the clamping area A, the second claw body 6022 is located at the bottom of the armrest bracket. In the absence of external force, during the armrest bracket is in place, the two clamping jaws 602 are automatically rotated by the armrest bracket, and the top ends of the clamping jaws 602 are displaced toward the center position of the clamping area A. The two clamping jaws 602 are in a closed state, so that the clamp 6 can lift and hold the armrest bracket.

[0047] To ensure that the first claws 6021 of the two clamping jaws 602 are aligned, the width of the second claw 6022 is smaller than that of the first claw 6021. During assembly, the second claws 6022 at the bottom of the two clamping jaws 602 can be docked at the lower part of the handrail bracket in a staggered manner.

[0048] See also Figure 2 When the lifting device is in use, the two ends of the double-sided pulling rod 3 are adjusted, and the two ends of the double-sided pulling rod 3 are adjusted to the height of the lifting device 1 and the lower end of the lifting device 1 are adjusted.

[0049] See also Figure 2 As shown, the base 1 is constructed as a disc, and a plurality of universal wheels 8 are evenly distributed circumferentially at the lower edge of the base 1. The universal wheels 8 are fixedly connected to the base 1 through fixing bolts 9. The lifting device can be moved at the construction site through the universal wheels 8, which is convenient to use.

[0050] See also Figure 1 、 2 As shown, in order to be able to adapt to different shapes and styles of handrail brackets for different project products, and to perform multi-angle adjustment according to the shape and size of the special-shaped handrail bracket, the lifting device includes a plurality of clamps 6, two adjacent clamps 6 are movably connected, and the overall length of the clamps 6 is extended so that the plurality of clamps 6 are flexible and can hold the handrail bracket in a chain-like manner;

[0051] See also Figure 2 、 6 As shown, preferably, a mounting groove 604 is formed on one side of the clamp 6, and a mounting block 605 is formed on the other side. When the two clamps 6 are connected, one clamp 6 is plugged into the mounting block 605 of the other clamp 6 through the mounting groove 604. The lifting device also includes a connecting member 7 that passes through the mounting groove 604 and the mounting block 605, and is used to flexibly connect the mounting groove 604 and the mounting block 605. The connecting member 7 is a bolt or a pin. In this embodiment, the connecting member 7 takes a hexagon socket bolt as an example. A through hole is formed on one side wall of the mounting groove 604, and a threaded hole is formed on the other side wall to connect with the hexagon socket bolt, so that the two adjacent clamps 6 can rotate around the hexagon socket bolt. When the connecting member 7 is a pin, both side walls of the mounting groove 604 are through holes. The pin cooperates with a cotter pin or other matching parts (such as a nut) to achieve the purpose of flexibly connecting the two adjacent clamps 6.

[0052] In the above technical solution, the utility model provides a lifting device for installing a special-shaped handrail bracket of a rail vehicle, and the method of use is as follows:

[0053] The installation lifting device can be used alone or in combination. When in use, first determine the number of devices needed based on the overall size of the handrail bracket, move the device to the use position, and then determine the number of clamps 6 used on a single lifting device based on the shape and posture of the handrail bracket to ensure the stability of the device when lifting the handrail bracket.

[0054] Secondly, drive the two-way twist rod 3 to rotate and adjust the height of the support rod to make the height of multiple lifting devices consistent. During the adjustment process, after the handrail bracket enters the clamping area A, the clamping claw 602 automatically lifts and holds the handrail bracket, and the handrail bracket tube is embedded in the clamping claw 602 of each clamp 6, and each clamp 6 is pressed down by the gravity of the handrail bracket tube to naturally lock the handrail bracket inward. After adjusting the handrail bracket to align with the installation position, rotate the two-way twist rod 3 at the same time to perform the lifting operation on the handrail bracket;

[0055] After the armrest bracket installation component reaches the installation position, fine-tune it. After the connection is tightened, rotate the two-way twist rod 3 in the opposite direction to drive the clamp 6 to move downward. The armrest bracket position is fixed, and the clamp 602 naturally releases the armrest bracket. The armrest bracket is installed.

[0056] Beneficial effects: The lifting device for installing the special-shaped handrail bracket can, firstly, be matched with handrail brackets of different pipe diameters within a certain specification range through the clamp 6. The clamp is automatically locked inward under the gravity of the handrail bracket, and automatically released otherwise without manual adjustment, thereby realizing handrail brackets of different shapes and styles suitable for different project products. Secondly, a number of clamps 6 are connected end to end in sequence to hold the handrail bracket in a chain-like flexible manner, thereby realizing multi-angle adjustment according to the shape and size of the special-shaped handrail bracket, which can be suitable for different shapes and styles of different project products and can provide sufficient strength and stability. In addition, the height of the support frame can be quickly and accurately adjusted and positioned through the two-way twist rod. Moreover, the base is movably supported by universal wheels, which is convenient to use.

[0057] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
