Description

Technical Field

[0001] The utility model relates to the technical field of tunnel equipment construction, and specifically relates to a positioning fixture for the spacing of hot-melt gaskets of a waterproof board for an open-cut tunnel. Background Technique

[0002] During the process of tunnel construction, a waterproof board is usually covered on the primary support concrete of the tunnel to make the waterproof board closely fit with the primary support concrete of the tunnel, so as to achieve the effect of preventing leakage.

[0003] During the construction of the waterproof board, in order to achieve the close fit between the waterproof board and the primary support concrete of the tunnel, hot-melt gaskets need to be welded at specific positions on the waterproof board. During the welding process of the hot-melt gaskets, it is necessary to first position the hot-melt gaskets by manual ruler measurement, and then use a hot-melt machine to weld the hot-melt gaskets on the waterproof board.

[0004] However, the method of manual ruler measurement for positioning is slow, and the distances measured manually are random, which will lead to inaccurate positioning, resulting in uneven distribution of the welded hot-melt gaskets, thus affecting the overall waterproof effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide a positioning fixture for the spacing of hot-melt gaskets of a waterproof board for an open-cut tunnel to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A positioning fixture for the spacing of hot-melt gaskets of a waterproof board for an open-cut tunnel, including a base, a first slide rail is fixedly arranged on the base, electric telescopic rods are fixedly installed at both ends of the first slide rail, and a second slide rail is fixedly arranged at the telescopic ends of the two groups of electric telescopic rods;

[0008] A positioning component is arranged on the second slide rail, including a central member fixedly arranged on the second slide rail and dispersing members equidistantly distributed on both sides of the central member with the central member as the symmetry center. Guide members are arranged on the dispersing members, and clamping structures for fixing the hot-melt gaskets are arranged on both the central member and the dispersing members;

[0009] A spacing adjustment component is arranged on the first slide rail, including a plurality of connecting members slidably arranged on the first slide rail at equal intervals. A group of the dispersing members or the central member is connected between adjacent two groups of the connecting members. When the electric telescopic rods act, the dispersing members will, under the cooperation of the connecting members and the guide members, expand or contract equidistantly to both sides of the central member with the central member as the center.

[0010] As a further solution of the utility model: the central member includes a fixed block fixedly arranged at the central position of the second slide rail, and the fixed block is hinged to two adjacent connecting members through two groups of the hinge rods.

[0011] As a further solution of the utility model: the dispersing member includes a second slider slidably arranged on the second slide rail, and the second slider is respectively connected to two adjacent connecting members through the hinge rod and a guiding member.

[0012] As a further solution of the utility model: the clamping structure includes two groups of clamping blocks symmetrically and slidably arranged on the fixed block or the second slider, the clamping blocks are also slidably connected to a slide rod fixedly arranged on the fixed block or the second slider, and a spring is also slidably arranged on the slide rod, one end of the spring abuts against the end of the slide rod, and the other end abuts against the clamping block.

[0013] As a further solution of the utility model: the connecting member includes a first slider, there are multiple groups of the first sliders, and multiple groups of the first sliders are equidistantly distributed on the first slide rail.

[0014] As a further solution of the utility model: the guiding member includes a guiding plate fixedly connected to the second slider, a fitting groove body is formed on the guiding plate, and the fitting groove body is connected to a fixed rod fixedly arranged on the first slider.

[0015] As a further solution of the utility model: the fitting groove body includes a stepped groove body structure formed by connecting multiple groups of inclined grooves and a horizontal groove, and a protruding column fixedly connected to the fixed rod is slidably arranged in the fitting groove body.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] By arranging the positioning assembly, the hot melt gaskets to be welded can be connected to the equidistantly distributed fixed blocks and the second sliders, so that the installation of multiple groups of hot melt gaskets can be accurately positioned at one time. Compared with the traditional manual ruler measurement and positioning method, it is faster.

[0018] At the same time, through the cooperation between the spacing adjusting assembly and the positioning assembly, by controlling the electric telescopic rod, the welding distance between the hot melt gaskets can be adjusted according to the actual situation on site and the material of the hot melt gaskets, so that the spacing between the hot melt gaskets is equal; after a group of hot melt gaskets are welded, one group of the welded hot melt gaskets is overlapped with the clamping structure at the end of the second slide rail, and then the four groups of hot melt gaskets in the next group can be accurately positioned. Repeat this process until the positioning welding of the entire waterproof board is completed. It is convenient and fast to use and has high positioning efficiency. Description of the Drawings

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0027] Please refer to Figures 1 to 5, in the embodiment of the present utility model, a spacing positioning fixture for a hot-melt gasket of a waterproof board in an open-cut tunnel includes a base 1, a first slide rail 3 is fixedly arranged on the base 1, electric telescopic rods 2 are fixedly installed at both ends of the first slide rail 3, and a second slide rail 4 is fixedly arranged at the telescopic ends of the two groups of electric telescopic rods 2;

[0028] Specifically, the above device is arranged on a lifting platform (not shown in the figure), and by adjusting the height of the lifting platform, the height between the second slide rail 4 and the ground can be changed, so as to adjust the welding height of the hot-melt gasket by using the positioning component subsequently.

[0029] The positioning component is arranged on the second slide rail 4, and includes a central member fixedly arranged on the second slide rail 4 and dispersing members equidistantly distributed on both sides of the central member with the central member as the symmetry center. Guide members are arranged on the dispersing members, and clamping structures for fixing the hot-melt gasket are arranged on both the central member and the dispersing members;

[0030] The central member includes a fixed block 7 fixedly arranged at the central position of the second slide rail 4, and the fixed block 7 is hinged to two adjacent connecting members through two groups of hinge rods 13;

[0031] The dispersing member includes a second slider 6 slidably arranged on the second slide rail 4, and the second slider 6 is respectively connected to two adjacent connecting members through the hinge rod 13 and the guide member;

[0032] Preferably, please refer to Figure 1 、 Figure 2 , there are four groups of the above dispersing members, and the four groups of dispersing members are equidistantly and symmetrically distributed on both sides of the fixed block 7 with the fixed block 7 as the symmetry center.

[0033] The clamping structure includes two groups of clamping blocks 8 symmetrically slidably arranged on the fixed block 7 or the second slider 6. The clamping blocks 8 are also slidably connected to a slide rod 9 fixedly arranged on the fixed block 7 or the second slider 6, and a spring 10 is also slidably arranged on the slide rod 9. One end of the spring 10 abuts against the end of the slide rod 9, and the other end abuts against the clamping block 8;

[0034] Specifically, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, a clamping block 8 is fixedly provided with a clamping block 801, and the clamping block 801 is slidably arranged in a clamping groove 701 formed in a fixed block 7 or a second slider 6. Under the cooperation of the clamping block 801 and the clamping groove 701, the clamping block 8 can only slide along the axial direction of the sliding rod 9. In particular, the above-mentioned spring 10 is always in a compressed state. At this time, the two compressed springs 10 will push the two clamping blocks 8 to approach each other. It should be added that the lower sides of the clamping blocks 8, the fixed block 7, and the second slider 6 are in the same plane (as Figure 3 shown), and the lower surface of the clamping block 8 is set as a smooth arc surface 802. During use, hold the base 1 by hand, face the smooth arc surface 802 towards the ground, and control the clamping block 8 to approach the hot-melt gasket placed on the ground. Until the arc surface 802 contacts the hot-melt gasket, continue to press the base 1 towards the ground. At this time, the extrusion generated between the hot-melt gasket and the clamping block 8 will push the two clamping blocks 8 away from each other, thereby further extruding the spring 10. Until the hot-melt gasket completely enters between the two clamping blocks 8, the elastic potential energy of the spring 10 will push the two clamping blocks 8 to have a tendency to approach each other, so that the hot-melt gasket is fixed on the fixed block 7 and the second slider 6. Subsequently, stand the whole device on the wall surface, and the subsequent installation of the hot-melt gasket can be accurately positioned, thereby facilitating the subsequent fixed installation.

[0035] The connecting member includes a first slider 5, and multiple groups of the first sliders 5 are provided. The multiple groups of the first sliders 5 are equidistantly distributed on the first slide rail 3;

[0036] Correspondingly, please refer to Figure 1 , Figure 2 , there are four groups of the above-mentioned first sliders 5, corresponding to the four intervals formed between the fixed block 7 and the second slider 6 respectively.

[0037] Please refer to Figure 1 , Figure 2 , Figure 5 , an open-cut tunnel waterproof board hot-melt gasket spacing positioning fixture further includes a spacing adjustment component, which is arranged on the first slide rail 3 and includes multiple groups of connecting members that are equidistantly slidably arranged on the first slide rail 3. A group of the dispersing members or the central member is connected between adjacent two groups of the connecting members. When the electric telescopic rod 2 acts, the dispersing member will, under the cooperation of the connecting member and the guiding member, diffuse or contract equidistantly to both sides of the central member with the central member as the center;

[0038] The guiding member includes a guiding plate 11 fixedly connected to the second slider 6. The guiding plate 11 is provided with a fitting groove body, and the fitting groove body is connected to a fixed rod 12 fixedly arranged on the first slider 5;

[0039] The fitting groove body includes a stepped groove body structure formed by connecting multiple groups of inclined grooves 1102 and horizontal grooves 1101. A protruding column 1201 fixedly connected to a fixing rod 12 is slidably arranged in the fitting groove body;

[0040] For details, please refer to Figure 1 , Figure 2 , the first slider 5 is located at the central position between two groups of second sliders 6 or between the fixed block 7 and the second slider 6. The distance between two adjacent first sliders 5 is equal to the distance between two groups of second sliders 6 on the second slide rail 4. In the initial state, the distance between the two first sliders 5 is the largest. At this time, the distance between the heat-melt gaskets connected to the fixed block 7 and the second slider 6 is the largest. The protruding column 1201 is located at the head end of the inclined groove 1102, and the second slide rail 4 is far from the first slide rail 3. By changing the distance between the second sliders 6, the welding distance between the heat-melt gaskets can be adjusted according to the actual situation on site and the material of the heat-melt gasket. For details, please refer to Figure 2 :

[0041] After the heat-melt gasket to be welded to the tunnel wall is connected to the fixed block 7 and the second slider 6, start the electric telescopic rod 2. The telescopic end of the electric telescopic rod 2 will pull the second slide rail 4 close to the first slide rail 3. At this time, due to the connection of the fixed-length hinge rod 13, the gradually decreasing second slide rail 4 will force the first sliders 5 to move away from each other. And during the movement away, the contact extrusion between the protruding column 1201 and the groove wall of the inclined groove 1102 will force the guide plates 11 distributed on both sides of the fixed block 7 to drive the second slider 6 to contract equidistantly towards the middle with the fixed block 7 as the symmetry center, thereby changing the distance between the heat-melt gaskets connected to the fixed block 7 and the second slider 6 to adapt to the heat-melt gasket welding work with different construction requirements. At the same time, with the cooperation of the clamping structure, the device standing in front of the wall can accurately position the welding position of the heat-melt gasket. After the welding is completed, overlap one group of heat-melt gaskets that have been welded with the clamping structure at the end of the second slide rail 4, and then the four groups of heat-melt gaskets in the next group can be accurately positioned. Repeat this process until the positioning welding of the entire waterproof board is completed. It is convenient and fast to use and has high positioning efficiency.
