[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 4As shown, on the one hand, the utility model provides a brake reset device for a launch site gate, the brake reset device is arranged between a door body 1 and a brake 2, the brake 2 is arranged above the door body 1, and the brake reset device for the launch site gate includes a bracket 3 fixed to the upper part of the door body 1, a guide wheel assembly 4 arranged at one end of the bracket 3 away from the door body 1, a hook 5 fixed to the lower part of the door body 1, and a pull rope 6 connected to the brake 2, wherein the guide wheel assembly 4 includes a support 41 fixed to the bracket 3, two connected to the end of the support 41 away from the bracket 3 A support plate 42, a pulley 43 arranged between the two support plates 42, and a fixed shaft 44 sleeved in the pulley 43. A copper sleeve 45 is sleeved between the pulley 43 and the fixed shaft 44. One end of the fixed shaft 44 is provided with a shoulder 46 that abuts against the side of the support plate 42, and the other end is provided with a limiting groove. A baffle 47 is inserted in the limiting groove. The size of the baffle 47 matches the limiting groove. The baffle 47 is fixed to the support plate 42 by a fastener. One end of the pull rope 6 is connected to the reset handle 21 provided on the brake 2, and the other end is provided with a handle 61. The pull rope 6 abuts against the outer periphery of the pulley 43.

[0025] The baffle 47 fixed by fasteners limits the axial position of the fixed shaft 44 .

[0026] Furthermore, in the brake resetting device for the launch site gate of the utility model, the copper sleeve 45 and the pulley 43 are in interference connection, and the copper sleeve 45 and the fixed shaft 44 are in clearance connection. Such an arrangement realizes a relatively rotatable connection relationship between the pulley 43 and the fixed shaft 44, and ensures the flexible rotation of the pulley 43 during operation.

[0027] Furthermore, in the brake resetting device for the launch site gate of the utility model, the length of the pull rope 6 matches the distance between the brake 2 and the hook 5. Of course, the specific size of the pull rope 6 needs to be set according to the actual use conditions such as the height of the door body 1, the position of the hook 5 and the brake 2.

[0028] As a specific implementation, in the brake resetting device of the launch site gate of the utility model, the pulley 43 is a V-shaped pulley. Such a configuration ensures that when the pull rope 6 slides in the guide wheel assembly 4, there is no side slip, and avoids the situation where the brake 2 handle is subjected to lateral force when the pull rope 6 is pulled and the brake 2 cannot be reset, thereby ensuring that the process of pulling the pull rope 6 is smoother.

[0029] As a specific implementation, in the brake resetting device of the utility model for the launch site gate, a triangular structure is formed between the bracket 3 and the door body 1. Such an arrangement enhances the stability between the bracket 3 and the door body 1 and ensures that the process of pulling the pull rope 6 is smoother.

[0030] Furthermore, in the brake resetting device for the launch site gate of the utility model, the size of the handle 61 matches the size of the hook 5. In this way, when the pull rope 6 is not pulled, the handle 61 can be hung on the hook 5.

[0031] As a specific implementation, in the brake resetting device of the utility model for the launch site gate, the fastener is a fastening bolt, and of course, it can also be other fasteners such as screws and rivets.

[0032] As a specific implementation, in the brake resetting device for the launch site gate of the utility model, the pull rope 6 is a nylon pull rope. Of course, the pull rope 6 can also be made of other materials such as metal and fiber, which is not limited here.

[0033] On the other hand, the present invention further provides a launch site gate, which includes the above-mentioned brake resetting device.

[0034] The working principle of the brake resetting device for the launch site gate of the present invention is specifically as follows:

[0035] When the device is not in daily use, the handle 61 at one end of the pull rope 6 is hung on the hook 5. When the brake 2 fails and cannot be reset automatically, the operator removes the handle 61 from the hook 5 and pulls the handle 61 downward. The handle 61 drives the pull rope 6 to move downward, and the pull rope 6 then pulls the reset handle 21 to complete the reset work.

[0036] In summary, compared with the prior art, the launch site gate and its brake reset device of the utility model have the following advantages and beneficial effects:

[0037] The device has a simple structure and is easy to assemble and disassemble. The V-shaped pulley arranged in the device ensures that the pull rope 6 does not slip sideways when sliding in the guide wheel assembly 4, thereby preventing the brake 2 handle from being subjected to lateral force and being unable to reset the brake 2 when the pull rope 6 is pulled. This ensures that the process of pulling the pull rope 6 is smoother, and realizes that there is no need to walk from the ground operating position to the brake 2 located above the gate to perform a manual reset operation, and the manual reset operation can be performed on the ground.

[0038] It should be noted that, in this article, unless otherwise clearly specified and limited, the term "connection" or its synonyms should be understood in a broad sense. For example, "connection" can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances. Moreover, expressions such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. At the same time, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a process, method, article or device. In addition, "front", "back", "left", "right", "upper", "lower" and the like in this article are all referenced to the placement state shown in the accompanying drawings.
