Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a crushing device used for road maintenance. Background Art

[0002] Road maintenance refers to the maintenance of the road surface when it is damaged and affects its use. When cracks or breaks appear on the road surface, during the maintenance process, it is necessary to use a crushing device to break up the damaged road and then refill it. Generally, when the area to be broken is large, large-scale crushing equipment is usually used for crushing. When the area to be broken and repaired is small, it is common to use small handheld crushing equipment for operation.

[0003] The existing handheld crushers used in road maintenance need to be manually picked up and moved during use. However, some handheld crushers are generally heavy, which consumes a lot of physical strength during the movement and is difficult to carry. Therefore, we propose a crushing device for road maintenance. Utility Model Content

[0023] like Figure 1-3 As shown, a crushing device for road maintenance includes a handheld crusher body 1 and a main fixing frame 8. Metal clamp seats 2 are provided at both ends of the upper part of the handheld crusher body 1, and a positioning clamp 3 is engaged with the outer side of the metal clamp seat 2. A rubber anti-skid pad is bonded to the inner wall of the metal clamp seat 2 to increase the friction between the metal clamp seat 2 and the positioning clamp 3. A bearing 4 is provided on the side of the positioning clamp 3 away from the vertical center line of the handheld crusher body 1, and a metal threaded rod 5 is provided on the outer side of the bearing 4. Side guide blocks 10 are provided on the front and rear ends of the outer side of the metal threaded rod 5. The main fixing frame 8 is provided on the side guide blocks 10. The main fixing frame 8 has a universal roller 11 at its four ends below, and the universal rollers 11 are fastened with bolts. During the road maintenance process, the staff uses the positioning clamp 3 to clamp and fix the handheld crusher body 1 on the inner side of the main fixing frame 8, and the main fixing frame 8 can support and fix the handheld crusher body 1. During the use of the handheld crusher body 1, the staff only needs to hold the main fixing frame 8, and then use the rolling of the universal roller 11 to move the handheld crusher body 1, thereby avoiding the phenomenon that the handheld crusher body 1 still needs to be manually carried, which can reduce the working difficulty of the handheld crusher body 1;

[0024] like Figure 1 and Figure 2As shown, a hydraulic telescopic rod 9 is fixedly installed in the middle of the upper inner side of the main fixed frame 8, four lateral guide blocks 10 are provided, and the lateral guide blocks 10 are slidably connected to the main fixed frame 8. After the handheld crusher body 1 is clamped and fixed on the inner side of the main fixed frame 8, the staff can use the characteristics of the hydraulic telescopic rod 9 that can be extended and contracted to drive the lateral guide blocks 10 and the metal threaded rod 5 to move up and down. At this time, the drill bit 7 provided below the handheld crusher body 1 can move up and down with it, so as to facilitate the use and movement of the handheld crusher body 1.

[0025] like Figure 1 As shown, a handle 6 is fastened to one end of the handheld crusher body 1 by bolts, and a drill bit 7 is provided at the bottom end of the handheld crusher body 1;

[0026] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a positioning assembly 12 is provided in the middle of the lower inner side of the main fixing frame 8, and the positioning assembly 12 includes a base plate 1201 and a positioning frame 1202, and the upper part of the base plate 1201 is integrally connected with the positioning frame 1202. When the handheld crusher body 1 needs to be fixed to the inner side of the main fixing frame 8, the positioning frame 1202 can assist in positioning the position of the drill bit 7, so as to facilitate the staff to snap the metal clamp seat 2 into the inner side of the positioning clamp 3, which is convenient for the later use of the handheld crusher body 1. Storage assemblies 13 are provided at both ends of the lower inner side of the main fixing frame 8, and the storage assembly 13 includes an embedded block 1301 and a storage disk 1302, and the storage disk 1302 is welded on the upper surface of the embedded block 1301, which is mainly used for storing equipment used in the road maintenance process. The cross-section of the embedded block 1301 is rectangular when viewed from the front, and a card slot corresponding to the size of the embedded block 1301 is opened inside the main fixing frame 8.

[0027] In summary, the crushing device for road maintenance, when used, first according to Figure 1-3 and Figure 5When the broken ground on the road surface needs to be broken and filled for repair, the staff holds the top handle of the handheld crusher body 1 and moves the drill bit 7 backward along the positioning clamp 3 until the metal clamp seat 2 is pushed to the inner side of the positioning clamp 3, and then holds the metal threaded rod 5 and rotates it clockwise. At this time, the positioning clamp 3 can be moved in the direction close to the center line of the handheld crusher body 1 under the action of the bearing 4, until the metal threaded rod 5 is rotated to the point where it cannot move. The two positioning clamps 3 can cooperate with each other to clamp and fix the handheld crusher body 1. At this time, the staff only needs to hold the main fixing frame 8, and then use the rolling of the universal roller 11 to move the handheld crusher body 1. When the handheld crusher body 1 is in use, after the staff starts the hydraulic telescopic rod 9, the hydraulic telescopic rod 9 can drive the lateral guide block 10 to slide up and down on the inner side of the main fixing frame 8 during the extension and contraction process. At this time, the metal threaded rod 5 and the drill bit 7 arranged below the handheld crusher body 1 can move up and down with it, thereby facilitating the use and movement of the handheld crusher body 1. Figure 4 and Figure 6 As shown, when the main fixed frame 8 is in use, the staff can place the materials used in the road maintenance process into the storage tray 1302 for storage. When the storage tray 1302 is idle, just hold the two sides of the storage tray 1302 and pull it upward with a little force. After the embedded block 1301 is completely separated from the main fixed frame 8, the storage tray 1302 can be removed. At the same time, because the bottom plate 1201 and the main fixed frame 8 are slidably connected, the staff holds the pull plate at the front end of the bottom plate 1201 and pulls it outward. After the bottom plate 1201 is completely separated from the main fixed frame 8, the storage assembly 13 can be removed.
