Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a concrete pavement roughening and crushing device. Background Technology

[0002] For traditional small-area / small-volume concrete breaking or road surface roughening, electric picks or pneumatic picks are typically used. To improve work efficiency and save workers' physical strength, existing construction companies are combining electric picks or pneumatic picks with mobile support structures. For example, CN222096580 discloses a roughening device, including a base, a support, a single-head roughening device, and a control rod. The base is equipped with rollers, the support is mounted on the base, and the single-head roughening device connects the base and the support. The chisel head of the single-head roughening device faces downwards and is located below the base. The control rod is connected to the support. In use, the worker holds the control rod and pushes the base across the concrete surface. After moving to a predetermined position, a slight press on the control rod causes the chisel head of the single-head roughening device to contact the concrete surface for roughening.

[0003] However, when the aforementioned chiseling device is used for long-distance transfer between different work locations or for post-work transfer, the operator needs to overcome the weight of the electric or pneumatic pick, raise the control lever, and then push the chiseling device forward. This can easily cause the chisel head of the electric or pneumatic pick to hit the ground, or even risk the chisel head falling and hitting the operator. Furthermore, when storing the chiseling device, due to the long length of the control lever, the chiseling device occupies too much horizontal space in the warehouse. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a concrete pavement roughening and crushing device. This device ensures reliability during device transfer, reduces the lateral space occupied when the device is stored, significantly reduces the direct impact force on workers, saves workers' physical energy, ensures workers' physical and mental health, improves work efficiency, and reduces construction costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A concrete pavement roughening and breaking device includes a base, a support, a roughening assembly, and a control rod. The support and the roughening assembly are located on opposite sides of the base. Two first moving mechanisms are fixed below the base on the side closest to the support. A second moving mechanism is movably connected below the base on the side closest to the roughening assembly via a first adjusting member. The first adjusting member has a first position and a second position corresponding to the second moving mechanism in a supported state and a non-supported state, respectively. The control rod is fixed to the upper end of the roughening assembly. One end of the control rod extends away from the base to form a handle. The other end of the control rod is movably connected to the upper end of the support via a hinge. The lower end of the roughening assembly is connected to the base via the second adjusting member. The second adjusting member has a third position and a fourth position corresponding to the roughening assembly in a vertical state and a horizontal state, respectively. When using the device for roughening operations, the second moving mechanism is positioned at the second position of the first adjusting member, and the roughening assembly is positioned at the third position of the second adjusting member. Pressing down the control lever causes the chisel head of the roughening assembly to roughen and break up the road surface. After the operation is completed, when the device is moved over a long distance or stored, the second moving mechanism is positioned at the first position of the first adjusting member, and the roughening assembly is positioned at the fourth position of the second adjusting member. At this time, the roughening assembly is in a horizontal state, and the base is stably supported by the three moving mechanisms. There is no need to lift the control lever when pushing the device forward, and the chisel head of the roughening assembly will not hit the ground, making it safe and reliable. Furthermore, the control lever and hinge are folded and stored on top of the base, reducing the lateral space occupied by the device.

[0007] Both the first and second moving mechanisms include casters and wheel posts fixed on caster bases. The upper end of the wheel post of the first moving mechanism is fixedly connected to the base, and the upper end of the wheel post of the second moving mechanism is movably connected to the first adjusting member.

[0008] The bracket includes connecting plates fixed above both sides of the base, and the upper ends of the two connecting plates are fixedly connected to the base to form a triangular structure.

[0009] The base has a through-type movable area in the middle. The first adjusting member includes two mounting plates fixed side by side on the base. There is a rotation gap between the two mounting plates that communicates with the movable area. The wheel column of the second moving mechanism is located in the rotation gap and is rotatably connected to the mounting plate via a rotating shaft. The two ends of each mounting plate extend outward from the base to form a lower locking part and an upper locking part. The lower locking part and the upper locking part are respectively provided with insertion holes representing a first position and a second position. The wheel column of the second moving mechanism has a locking hole that can be detachably connected to any of the insertion holes via a first pin.

[0010] The second adjusting component includes an upper ear seat fixed to the upper surface of the base, a side ear seat fixed to the outside of the base, and a limiting ring fixed to the outside of the chiseling assembly. The upper ear seat and the side ear seat are respectively provided with pin holes representing the third position and the fourth position. The limiting ring is fixed with an ear plate that cooperates with the upper ear seat / side ear seat, and the ear plate is detachably connected to any of the pin holes via a second pin.

[0011] The hinge includes a hinge seat fixed to the upper end of the bracket, a rotary joint rotatably connected to the end of the control rod, and a hinge rod whose two ends are respectively rotatably connected to the hinge seat and the rotary joint. The hinge seat has a positioning part extending horizontally away from the bracket, and the positioning part has a positioning hole. The hinge rod has a connecting hole near the end connected to the hinge seat, which is detachably connected to the positioning hole via a positioning pin. Adding a rotary joint between the hinge rod and the control rod can prevent interference between the control rod and the hinge rod when the control rod is stored.

[0012] The outer side of the ear plate has a limiting surface parallel to the longitudinal axis of the chiseling assembly. When the chiseling assembly is in a horizontal state, the limiting surface is in contact with the upper surface of the base.

[0013] A trolley handle is fixedly inserted through the upper end of the bracket.

[0014] The control rod is connected to the chiseling assembly by a metal strap, and the control rod and the chiseling assembly are in elastic contact via a rubber pad. The rubber pad can buffer the vibration generated by the chiseling assembly during operation, thereby reducing its reverse impact force on the worker, improving work comfort, and protecting the physical and mental health of the worker.

[0015] This utility model has the following beneficial effects:

[0016] This invention features an adjustable second moving mechanism and an adjustable chiseling assembly mounted on a base. When chiseling is being performed, the second moving mechanism is positioned at the second position of the first adjusting member, and the chiseling assembly at the third position. Pressing down the control lever causes the chisel head of the chiseling assembly to chisel and break up the road surface. After the work is completed, for long-distance transport or storage, the second moving mechanism is positioned at the first position of the first adjusting member, and the chiseling assembly at the fourth position. In this position, the chiseling assembly is horizontal, and the base is stably supported by the three moving mechanisms. There is no need to lift the control lever during the device's forward movement, and the chisel head will not hit the ground, ensuring safety and reliability. Furthermore, the control lever and hinge are folded and stored on top of the base, reducing the device's lateral space requirements, improving work efficiency, and lowering construction costs.

[0030] like Figures 1-5As shown, this utility model provides a concrete pavement roughening and breaking device, including a base 1, a support 2, a roughening assembly 3, and a control rod 4. The support 2 and the roughening assembly 3 are located on both sides of the base 1. The roughening assembly 3 is the same as in the prior art, using a pneumatic pick or an electric pick, with the chisel head facing downwards and located below the base 1. The support 2 includes connecting plates 201 fixed above both sides of the base 1. The upper ends of the two connecting plates 201 are fixedly connected to the base 1 to form a triangular structure. The support 2 and the base 1 form a triangular structure, ensuring the strength of the device while reducing its weight. Two first moving mechanisms 6 are fixed below the side of the base 1 near the support 2. The side of the base 1 near the roughening assembly 3 is movably connected via a first adjusting member 8. The device includes a second moving mechanism 7. The first adjusting member 8 has a first position and a second position corresponding to the second moving mechanism 7 in a supported state and a non-supported state, respectively. The control rod 4 is fixed to the upper end of the chiseling assembly 3. One end of the control rod 4 extends away from the base 1 to form a handle. The other end of the control rod 4 is movably connected to the upper end of the bracket 2 via a hinge 5. The control rod 4 extends the lever arm that the operator directly applies to the working device, greatly reducing the downward pressure on the operator and reducing the operator's physical exertion. The lower end of the chiseling assembly 3 is connected to the base 1 via a second adjusting member 9. The second adjusting member 9 has a third position and a fourth position corresponding to the chiseling assembly 3 in a vertical state and a horizontal state, respectively.

[0031] When using the device for roughening operations, such as Figure 1 As shown, the second moving mechanism 7 is positioned at the second position of the first adjusting member 8, and the chiseling assembly 3 is positioned at the third position of the second adjusting member 9. Pressing down the control lever 4 causes the chisel head of the chiseling assembly 3 to chisel and break up the road surface. After the operation is completed, when the device is moved long distances or stored, such as... Figure 4 As shown, the second moving mechanism 7 is set in the first position of the first adjusting member 8, and the chiseling assembly 3 is set in the fourth position of the second adjusting member 9. At this time, the chiseling assembly 3 is in a horizontal state, and the base 1 is stably supported by the three moving mechanisms. During the process of pushing the device forward, there is no need to lift the control rod 4, and the chisel head of the chiseling assembly 3 will not hit the ground. It is safe and reliable. The control rod 4 and the hinge 5 are folded and stored on the top of the base 1, which reduces the lateral space occupied by the device.

[0032] Specifically, both the first moving mechanism 6 and the second moving mechanism 7 include a caster wheel 601 and a wheel post 602 fixed on the base of the caster wheel 601. The upper end of the wheel post 602 of the first moving mechanism 6 is fixedly connected to the base 1, and the upper end of the wheel post 602 of the second moving mechanism 7 is movably connected to the first adjusting member 8.

[0033] The base 1 has a triangular base composed of three base plates connected in pairs. Therefore, the base 1 has a through-type movable area 101 in the middle. The first moving mechanism 6 is located below the two bottom corners corresponding to the lower end of the connecting plate 201 of the bracket 2, and the second moving mechanism 7 is located below the other foot.

[0034] like Figure 3 and Figure 6 As shown, the first adjusting member 8 includes two mounting plates 801 fixed side by side on the base 1. The two mounting plates 801 have a rotation gap 804 that communicates with the movable area 101. The wheel column 602 of the second moving mechanism 7 is located within the rotation gap 804 and is rotatably connected to the mounting plates 801 via a rotating shaft. Both ends of each mounting plate 801 extend outward from the base 1 to form a lower locking part 802 and an upper locking part 803. The lower locking part 802 and the upper locking part 803 are respectively provided with insertion holes 805 representing a first position and a second position. The wheel column 602 of the second moving mechanism 7 has a locking hole that is detachably connected to any of the insertion holes 805 via a first pin 806.

[0035] like Figure 3 and Figure 6 As shown, the second adjusting member 9 includes an upper ear seat 902 fixed to the upper surface of the base 1, a side ear seat 901 fixed to the outside of the base 1, and a limiting ring 10 fixed to the outside of the chiseling assembly 3. The upper ear seat 902 and the side ear seat 901 are respectively provided with pin holes representing the third position and the fourth position. The limiting ring 10 is fixed with an ear plate 1001 that cooperates with the upper ear seat 902 / side ear seat 901, and the ear plate 1001 is detachably connected to any of the pin holes via a second pin.

[0036] To ensure the chiseling assembly 3 is placed more stably on the base 1, the outer side of the ear plate 1001 has a limiting surface 1002 parallel to the longitudinal axis of the chiseling assembly 3. When the chiseling assembly 3 is in a horizontal state, the limiting surface 1002 contacts the upper surface of the base 1, which can prevent the chiseling assembly 3 from tilting backward under its own weight. When the chiseling assembly 3 is in a vertical state, the limiting surface 1002 contacts the surface of the side ear seat 901, thereby reducing the shaking amplitude of the chiseling assembly 3 during operation.

[0037] The control rod 4 is connected to the chiseling assembly 3 by a metal strap 12, so that the chiseling assembly 3 can be detached and installed. More preferably, in order to reduce the directional impact force on the operator when the chiseling assembly 3 is working, the control rod 4 and the chiseling assembly 3 are in elastic contact through a rubber pad 11.

[0038] like Figure 5 and Figure 7As shown, the hinge 5 includes a hinge seat 503 fixed to the upper end of the bracket 2, a rotary joint 502 rotatably connected to the end of the control rod 4, and a hinge rod 501 with both ends rotatably connected to the hinge seat 503 and the rotary joint 502 respectively. The hinge seat 503 has a positioning part 504 extending horizontally away from the bracket 2, and a positioning hole is provided on the positioning part 504. The hinge rod 501 has a connecting hole 505 near the end connected to the hinge seat 503, which is detachably connected to the positioning hole via a positioning pin 506. The addition of the rotary joint 502 between the hinge rod 501 and the control rod 4 can prevent interference between the control rod 4 and the hinge rod 501 when the control rod 4 is stored. At the same time, the positioning pin 506 is used to switch the connection state between the hinge rod 501 and the hinge seat 503 to ensure the normal use of the device.

[0039] To facilitate the transfer of the device, a trolley handle 13 is fixedly inserted through the upper end of the bracket 2.

[0040] When implementing this technical solution, the chiseling component 3 used is an electric chisel, such as... Figure 3 As shown, the second moving mechanism 7 is rotated around the pivot to above the base 1, and the wheel column 602 is fixed to the upper locking part 803 using the first pin 806. The ear plate 1001 on the limiting ring 10 at the lower end of the electric pick is inserted into the side ear seat 901 and fixed by the second pin. At this time, the hinge rod 501 is kept horizontal. The connecting hole 505 on the hinge rod 501 and the positioning hole on the hinge seat 503 are aligned and fixed by the positioning pin 506. The control rod 4 is set horizontally under the drive of the hinge rod 501. The operator holds the handle and presses down on the control rod 4. The entire device rotates around the axle of the universal wheel 601 of the first moving mechanism 6. The chisel head of the electric pick roughens and breaks up the concrete road surface to be processed. When the work is finished and a long distance transfer or storage is required, such as Figure 5 As shown, remove the first pin 806, rotate the wheel column 602 of the second moving mechanism 7 downward, and use the first pin 806 to fix the wheel column 602 to the lower locking part 802. At this time, the three moving mechanisms jointly support the base 1. Remove the second pin and the positioning pin 506, fold the control rod 4 and the hinge rod 501, place the electric pick horizontally on the upper ear seat 902 and fix it with the second pin. The operator holds the trolley handle 13 and pushes it to the designated position. When storing the device, since the control rod 4 has been folded, its lateral space is greatly reduced, making it easy to store.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
