Description

Technical Field

[0001] This utility model relates to the field of descent buffer valve support technology, specifically a descent buffer valve support with emergency insurance. Background Technology

[0002] The drop buffer valve bracket is mainly used for support during valve body maintenance. The currently used drop buffer valve bracket is mainly composed of an upper plate, a lower plate, and a buffer connecting rod. However, the three are integrated into one structure and made of steel. It is carried during maintenance. The existing drop buffer valve bracket does not have an emergency safety function, which may cause the drop buffer valve bracket to drop under excessive force, posing a danger to the maintenance personnel. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a descent buffer valve bracket with emergency safety, thereby solving the problem that the existing descent buffer valve brackets mentioned in the background technology do not have an emergency safety function, which may cause the descent buffer valve bracket to fall under excessive force, posing a danger to the maintenance personnel.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a descent buffer valve bracket with emergency safety, comprising a valve bracket structure, wherein an adjustment limiting structure is fixedly installed between the valve bracket structures;

[0005] The valve support structure includes a lower plate as a base, and a buffer adjustment rod is fixed above the lower plate, while an upper plate is fixed above the buffer adjustment rod.

[0006] A limit rod is fixed to the surface of the buffer adjustment rod, and a locking rod is rotatably installed above the surface of the buffer adjustment rod via a bearing rod.

[0007] By adopting the above technical solution, the bearing rod is installed to achieve a matching installation connection.

[0008] Preferably, the adjustment and limiting structure includes a bearing mounting seat fixed below the lower plate body, and a threaded cylinder with a rudder disc on the surface is fixed on the bearing mounting seat. At the same time, a threaded rod is installed in the threaded cylinder, and one end of the threaded rod is fixedly connected to the lower part of the upper plate body through a connecting block.

[0009] By adopting the above technical solution, the threaded cylinder is used to adjust the rotation thread.

[0010] Preferably, there are two sets of limiting rods, and each set of limiting rods has four rods.

[0011] By adopting the above technical solution, the limiting rod is set to achieve locking and limiting.

[0012] Preferably, one set of buffer adjustment rods is provided, and the buffer adjustment rods are symmetrically arranged about the center line of the lower plate.

[0013] By adopting the above technical solution, the installation height at both ends is adjusted by setting a buffer adjustment rod.

[0014] Preferably, there are two clamping rods, and the clamping rods are symmetrically arranged about the axis of the lower plate.

[0015] By adopting the above technical solution, the locking lever is designed to achieve rotational locking and limiting.

[0016] Preferably, the bearing mounting base, rudder disc, and threaded cylinder are connected in a "V" shape.

[0017] By adopting the above technical solution, the rudder disc is installed to achieve a through-hole fixed installation.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the descent buffer valve bracket with emergency safety features...

[0019] (1) This case solves the problem that the existing descent buffer valve support does not have an emergency safety function by setting up a valve support structure. This would cause the descent buffer valve support to fall when subjected to excessive force, which would be dangerous for the maintenance personnel. When the upper plate body drives the buffer adjustment rod to adjust the force, the operator rotates the locking rod to make the locking rod engage with the limit rod to limit the position. When the limit rod engages with the locking rod to limit the position, the above problem is avoided.

[0020] (2) By setting the limit structure, the above problems are solved. When the upper plate is subjected to force adjustment, the operator rotates the rudder. When the rudder is subjected to force, it drives the threaded cylinder to rotate synchronously. When the threaded cylinder is subjected to force and rotates, it drives the threaded rod to rise and fall in a certain distance. By changing the distance of the threaded rod's rotation and rise and fall, the upper plate is adjusted synchronously. By keeping the upper plate and the threaded rod synchronized, the above problems are avoided. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a descent buffer valve bracket with emergency safety, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a valve support structure 1, which includes a lower plate 101 as a base. A buffer adjustment rod 102 is fixed above the lower plate 101. One set of buffer adjustment rods 102 is provided, and the rods are symmetrically arranged about the center line of the lower plate 101. The presence of two rods in one set demonstrates the synchronous force support and adjustment capabilities of the components. Furthermore, the presence of two rods in one set also reflects the practicality and axial symmetry of the component installation. An upper plate 103 is fixed above the buffer adjustment rod 102. Limiting rods 104 are fixed to the surface of the buffer adjustment rod 102. Two sets of limiting rods 104 are provided, with four rods in each set. The above components... When there are 2 groups of 8 components, this not only reflects the symmetrical distribution and installation of the above-mentioned components, but also the locking and limiting function of the above-mentioned components. Furthermore, the arrangement of 2 groups of 8 components simultaneously reflects the practicality of the installation and the aesthetic appeal of the equidistant distribution of the above-mentioned components. Moreover, a locking rod 106 is rotatably mounted above the surface of the buffer adjustment rod 102 via a bearing rod 105. There are 2 locking rods 106, and the locking rods 106 are symmetrically arranged about the axis of the lower plate 101. The arrangement of 2 components not only reflects the individual or synchronous rotation adjustment of the above-mentioned components, but also provides locking and limiting for the single or two buffer adjustment rods 102 during individual or synchronous rotation adjustment. Furthermore, the arrangement of 2 components simultaneously reflects the practicality of the rotation adjustment of the above-mentioned components.

[0028] like Figure 4 As shown, an adjustment and limit structure 2 is fixedly installed between valve support structures 1. The adjustment and limit structure 2 includes a bearing mounting seat 201 fixed below the lower disc body 101, and a threaded cylinder 202 with a steering wheel 203 on its surface is fixed on the bearing mounting seat 201. The connection shapes of the bearing mounting seat 201, the steering wheel 203, and the threaded cylinder 202 are arranged in a "plus" structure. When the connection shapes of the above three are arranged in a "plus" structure, it not only reflects the integrity of the installation of the above three, but also reflects the force rotation adjustment of the above three. And when the connection shapes of the above three are arranged in a "plus" structure, the axial and longitudinal axis symmetry of the installation of the above three is reflected. At the same time, a threaded rod 204 is installed in the threaded cylinder 202 in a matching manner. One end of the threaded rod 204 is fixedly connected to the lower part of the upper disc body 103 through a connecting block 205. Among them, the above components constitute a rotary lifting adjustment structure. When using the rotary lifting adjustment structure composed of the above components, the rotary lifting interval distance of the threaded rod 204 is effectively changed. By changing the rotary lifting interval distance of the threaded rod 204, the upper disc body 103 is effectively supported by synchronous lifting and adjustment.

[0029] In the above solution, when the upper disc body 103 drives the buffer adjustment rod 102 to be adjusted under force, at this time, the operator rotates the clamping rod 106 to engage and limit the clamping rod 106 with the limiting rod 104. When the upper disc body 103 is adjusted under force, at this time, the operator rotates the steering wheel 203 to move. When the steering wheel 203 is forced to move, it带动 the threaded cylinder 202 to rotate synchronously under force. When the threaded cylinder 202 rotates under force, it带动 the lifting interval distance of the threaded rod 204. By changing the rotary lifting interval distance of the threaded rod 204, the adjusted upper disc body 103 can be kept under synchronous drive adjustment.
