Abstract
Description
Technical Field
[0001] This utility model relates to the field of road maintenance technology, and in particular to a road maintenance joint treatment device. Background Technology
[0002] Road maintenance is the upkeep and maintenance of roads. Treating road surface cracks is an important part of the road maintenance process. By treating road surface cracks, we can effectively prevent the cracks from expanding further, thereby ensuring the overall quality of the road surface. In the process of treating road surface cracks, a trowel is needed to evenly apply the repair material to the cracks to achieve a better repair effect. Therefore, a trowel is an indispensable piece of equipment in road surface crack treatment.
[0003] Currently, existing trowels for crack treatment have a relatively simple structure, mainly consisting of a trowel blade and a handle. However, because the trowel blade is relatively thin, it has sharp edges. When workers transport the trowel, they place it directly into their tool bag. The sharp edges of the trowel can easily damage other tools in the tool bag during transport, which limits its use. Therefore, we propose a road maintenance crack treatment device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a road surface maintenance crack treatment device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A road surface maintenance crack treatment device includes a trowel with a handle welded to its top. A support frame is provided on the upper side of the trowel, and a receiving groove is opened on the side wall of the support frame. A connecting rod is inserted into the receiving groove, and slots are symmetrically opened on both sides of the connecting rod. Insertion rods are inserted into the slots. The sides of the two sets of insertion rods that are close to each other are connected to the inner wall of the slots through a connecting spring. A protective block is connected to the sides of the two sets of insertion rods that are far apart from each other, and the longitudinal section of the protective block is set as a U-shaped structure.
[0007] Preferably, guide rods are symmetrically connected above the connecting rod, and the support frame has through grooves adapted to the guide rods inside.
[0008] Preferably, each of the protective blocks is connected to a handle on its upper surface, and the outer surface of the handle is covered with an anti-slip sleeve.
[0009] Preferably, the bottom end of the support frame is symmetrically welded with mounting plates, and the interior of the mounting plates is connected to the upper surface of the trowel by bolts.
[0010] Preferably, a limiting pin is inserted laterally on one side of the support frame, and two sets of positioning grooves that are adapted to the limiting pin are opened on the side wall of the guide rod.
[0011] Preferably, the end of the connecting spring is symmetrically connected to a movable block, and the side wall of the connecting rod is provided with a sliding groove that matches the movable block.
[0012] Preferably, the protective block is symmetrically fitted with a guard edge, and the end of the guard edge is set as an arc-shaped structure.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This device is equipped with protective blocks and a support frame. After use, the operator can pull two sets of protective blocks to cover the edge of the spatula, which can effectively prevent the sharp edges of the spatula from accidentally damaging other tools during transportation, thereby improving the safety of the device during use.
[0015] 2. The device is equipped with a guide rod and a limiting pin. During use, the guide rod can effectively ensure the stability of the connecting rod during vertical movement, and the insertion of the limiting pin can limit the guide rod to prevent it from swaying up and down after being lifted.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-4 A road surface maintenance crack treatment device includes a trowel 1, a handle 12 welded to the top of the trowel 1, a support frame 2 on the upper side of the trowel 1, and a receiving groove 10 on the side wall of the support frame 2. A connecting rod 3 is inserted into the receiving groove 10, and slots are symmetrically opened on both sides of the connecting rod 3. Insertion rods 4 are inserted into the slots. The side of the two sets of insertion rods 4 that are close to each other is connected to the inner wall of the slot through a connecting spring 5. A protective block 6 is connected to the side of the two sets of insertion rods 4 that are far apart from each other. The longitudinal section of the protective block 6 is set with a U-shaped structure. The U-shaped protective block 6 can effectively improve the protection effect on the side wall of the trowel 1.
[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that guide rods 7 are symmetrically connected above the connecting rod 3, and the support frame 2 has a through groove that matches the guide rod 7. As the connecting rod 3 moves up and down with the protective block 6, the guide rod 7 connected to the top of the connecting rod 3 can slide on the inner wall of the through groove to guide the connecting rod 3 and effectively prevent the connecting rod 3 from shifting left and right.
[0024] Furthermore, refer to Figure 1 and Figure 2 It can be seen that handles 13 are connected to the top of the protective blocks 6 respectively, and the outer surface of the handles 13 is covered with anti-slip sleeves. Through the cooperation of the handles 13 and the anti-slip sleeves, it is convenient for the staff to pull the two sets of protective blocks 6 to move laterally, so that the two sets of protective blocks 6 can move away from each other, and thus the two sets of protective blocks 6 can be moved smoothly to the outside and top of the support frame 2.
[0025] Furthermore, refer to Figure 4 It can be seen that the bottom end of the support frame 2 is symmetrically welded with mounting plates 9, and the interior of the mounting plates 9 is connected to the upper surface of the trowel 1 by bolts. By setting the mounting plates 9 and bolts, the support frame 2 can be disassembled so that the support frame 2 and the protective block 6 can be reused.
[0026] Furthermore, refer to Figure 4It can be seen that a limiting pin 14 is inserted horizontally on one side of the support frame 2, and two sets of positioning grooves adapted to the limiting pin 14 are opened on the side wall of the guide rod 7. The limiting pin 14 is composed of a set of horizontal insert rods and a set of pulling blocks. When the limiting pin 14 is inserted into the positioning groove above the guide rod 7, the two sets of protective blocks 6 can cover the periphery of the spatula 1. When it is inserted into the positioning groove below the guide rod 7, the two sets of protective blocks 6 can be pushed to the top of the spatula 1 to ensure the normal use of the spatula 1.
[0027] Furthermore, refer to Figure 4 It can be seen that the ends of the connecting springs 5 are symmetrically connected with moving blocks 8, and the side wall of the connecting rod 3 is provided with a sliding groove that matches the moving blocks 8. Through the cooperation of the moving blocks 8 and the sliding groove, the stability of the two sets of connecting springs 5 when moving inside the connecting rod 3 can be guaranteed.
[0028] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the protective block 6 is symmetrically fitted with a guard 11, and the end of the guard 11 is set with an arc structure. Through the two sets of arc structure guards 11, the edge of the protective block 6 can be protected, thereby effectively preventing the edge of the protective block 6 from being damaged by bumps, thus ensuring its protective effect on the spatula 1.
[0029] Working principle: When using this utility model, the worker can first fill the gaps in the road with filling material, and then smooth the filling material by holding the handle 12. After completing the road surface treatment, the worker can first clean the device, and then pull the limiting pin 14 out from the support frame 2 and guide rod 7. Then, by manually pulling the two sets of handles 13, the worker can cause the two sets of protective blocks 6 to be moved away from each other. Then, the worker can push down the handles 13, so that the position of the protective blocks 6 corresponds to the position of the support frame 2. At this time, the two sets of protective blocks 6 can be locked into both sides of the trowel 1 by the elastic force of the connecting spring 5, so as to cover the side of the trowel 1. The two sets of U-shaped protective blocks 6 can effectively prevent the edge of the trowel 1 from accidentally injuring other tools.
[0030] When the spatula 1 needs to be used, the worker only needs to pull the handle 13 again to move the two sets of protective blocks 6 away from each other. Then, by pushing the handle 13 upward, the protective blocks 6 and the connecting rod 3 will be raised together. At this time, the two sets of protective blocks 6 will move closer to each other due to the elastic force of the connecting spring 5 and will move above the spatula 1, so that the worker can use the spatula 1 normally for smoothing work. The above is the complete working principle of this utility model.
[0031] In this utility model, the installation, connection or setting methods of all the components mentioned above are common mechanical methods, and the specific structure, model and coefficient index of all the components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
