Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of component cushion blocks, in particular to a cushion block used for stacking shield segments. Background Art
[0002] The shield segment is the main assembly component of shield construction and the innermost barrier of the tunnel. It is responsible for resisting soil pressure, groundwater pressure and some special loads. The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof and durability of the tunnel. The production of shield segments usually adopts high-strength anti-seepage concrete to ensure reliable bearing and waterproof performance. The production mainly uses the finished segment mold which can be formed after sealing and pouring concrete.
[0003] When stacking the segments, it is necessary to place a pad at the bottom of the segments. Existing pads all use a wooden pad, but the structure of the wooden pad is relatively simple. After use, it is not convenient to store it, which makes it easy to lose it, increasing the cost of use. Therefore, a pad for stacking shield segments is proposed to solve the above problem. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a spacer block for stacking shield segments, which has the advantages of being easy to use and store, and solves the problems mentioned in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cushion block for stacking shield segments, comprising a cushion block, wherein the interior and the outer surface of the cushion block are both provided with connection components;
[0006] The connecting assembly includes a connecting column fixedly connected to the right side of the cushion block, a push block fixedly connected to the right side of the connecting column, a cavity is opened inside the cushion block, a spring is fixedly connected inside the cushion block, a connecting plate is arranged inside the cushion block, a fixing column is fixedly connected to the side of the connecting plate away from the spring, and a clamping block is fixedly connected to the side of the fixing column away from the spring.
[0007] Furthermore, a reinforcing plate is fixedly connected to the top of the cushion block, and an elastic anti-slip pad is fixed to the top of the reinforcing plate.
[0008] Furthermore, a handle is fixedly connected to the front side of the cushion block, and an outer surface of the handle is provided with anti-slip grooves.
[0009] Furthermore, a limiting groove is provided inside the cushion block, a sliding connection limiting block is defined inside the limiting groove, and the limiting block is fixedly connected to the connecting plate.
[0010] Furthermore, one end of the spring close to the connecting plate is fixedly connected to the connecting plate, and the size of the cavity is larger than the size of the push block.
[0011] Furthermore, the cross-sectional shape of the clamping block is a trapezoid, and the inclination angle of the inclined surface of the pushing block is the same as the inclination angle of the inclined surface of the clamping block.
[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0013] The pad block for stacking shield segments, when it is necessary to store the pad block, align the push block of one pad block with the cavity of the other pad block and move it to the side close to the cavity. When the push block squeezes the clamping block, the clamping block will be forced to move to the side close to the connecting plate and compress the spring at the same time. When a certain force is applied, the push block will be completely clamped into the cavity. At the same time, the inclined surface on the right end of the clamping block will limit the push block, so that the two pad blocks can be spliced and stored, making it easy to store and not easy to lose.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-3 A spacer block for stacking shield segments in this embodiment includes a spacer block 1, and a connecting component 2 is provided inside and on the outer surface of the spacer block 1.
[0020] The connection assembly 2 includes a connection column 201 fixedly connected to the right side of the cushion block 1, a push block 202 fixedly connected to the right side of the connection column 201, a cavity 203 is provided inside the cushion block 1, and the size of the cavity 203 is larger than the size of the push block 202. A spring 204 is fixedly connected inside the cushion block 1, and a connection plate 205 is provided inside the cushion block 1. One end of the spring 204 close to the connection plate 205 is fixedly connected to the connection plate 205, and a fixing column 206 is fixedly connected to the side of the connection plate 205 away from the spring 204.
[0021] Secondly, a block 207 is fixedly connected to the side of the fixed column 206 away from the spring 204. The cross-section of the block 207 is a trapezoid. The inclination angle of the inclined surface of the push block 202 is the same as that of the inclined surface of the block 207. One block 207 is provided with four inclined surfaces. A limiting groove 209 is provided inside the cushion block 1. The limiting groove 209 limits the sliding connection limiting block 208 inside. The limiting block 208 is fixedly connected to the connecting plate 205. By providing the limiting groove 209 and the limiting block 208, the connecting plate 205 can be made more stable when sliding up and down.
[0022] In addition, a reinforcing plate 4 is fixedly connected to the top of the cushion block 1, and an elastic anti-skid pad 5 is fixed to the top of the reinforcing plate 4, which can increase the friction between the top of the cushion block 1 and the pipe segment. A handle 3 is fixedly connected to the front of the cushion block 1, and the outer surface of the handle 3 is provided with anti-skid patterns. By providing the handle 3, the cushion block 1 can be easily taken.
[0023] The working principle of the above embodiment is:
[0024] The pad block for stacking shield segments, when the pad block 1 needs to be stored, the push block 202 of one pad block 1 is aligned with the cavity 203 of the other pad block 1, and moved to the side close to the cavity 203. When the push block 202 squeezes the clamping block 207, the clamping block 207 is forced to move to the side close to the connecting plate 205, and at the same time compresses the spring 204. When a certain force is applied, the push block 202 will be completely clamped into the cavity 203, and at the same time, the right end slope of the clamping block 207 will limit the push block 202, so that the two pad blocks 1 can be spliced and stored, making it convenient to store the pad blocks 1 and not easy to lose.
