Description

Technical Field

[0001] This utility model belongs to the field of road joint strip technology, and in particular relates to a concrete road joint strip trolley. Background Technology

[0002] Concrete pavement joint strips are devices used at the joints of concrete pavements. They mainly serve to seal the joints, prevent debris from entering the joints, reduce water penetration, and to a certain extent, accommodate the expansion and contraction deformation between concrete pavement slabs. After placing the joint strips in the concrete joints, a strip compactor is needed to compact them.

[0003] Currently, most existing joint pressing strip devices use a single pressing wheel. However, concrete joints have different widths. When pressing joint pressing strips of different widths, the pressing wheel needs to be replaced manually. The replacement process is not only cumbersome and labor-intensive, but also reduces the efficiency of joint pressing strips. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a concrete pavement joint pressing strip trolley. By setting a rotating turntable in the through groove of the trolley body, and setting four pressing wheels of different widths (pressing wheel one, pressing wheel two, pressing wheel three, and pressing wheel four) around the turntable, the trolley can freely select when pressing joint pressing strips of different widths, avoiding the trouble of manually changing the pressing wheels, greatly reducing the intensity of manual labor, and improving work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A concrete pavement joint stripping trolley includes a vehicle body with two symmetrical counterweights on the body. Two symmetrical push rods are fixed to the upper right side of the vehicle body, with handles fixed to the inner upper ends of the push rods. Support legs are fixed around the bottom of the vehicle body, each support leg having an internal thread for threaded connection to a screw. A roller seat is fixed to the bottom of the screw, and a roller is rotatably connected to the roller seat. A through groove is formed in the middle of the vehicle body. Fixing plates are fixed at both the front and rear ends of the bottom of the vehicle body. A turntable is rotatably connected to the fixing plates via a first rotating shaft. The turntable is rotatably connected to the through groove in the middle of the vehicle body. Four fixing seats are fixed around the turntable, equidistantly arranged around its central axis. The inner sides of each fixing seat are connected via a second rotating shaft. The system is rotatably connected by four pressing wheels: pressing wheel one, pressing wheel two, pressing wheel three, and pressing wheel four. The width of pressing wheel one is greater than the width of pressing wheel two, the width of pressing wheel two is greater than the width of pressing wheel three, and the width of pressing wheel three is greater than the width of pressing wheel four. A limiting mechanism is provided between the vehicle body and the turntable. By setting a rotating turntable in the through groove of the vehicle body and setting four pressing wheels of different widths around the turntable, the system can freely select the pressing wheels when pressing seam pressing strips of different widths, avoiding the trouble of manually changing the pressing wheels, greatly reducing the labor intensity and improving the work efficiency. By setting a counterweight on the vehicle body, a good pressing force is ensured for the seam pressing strips. By setting adjustable support legs and screws, it can be used for seam pressing strips of different depths.

[0007] Furthermore, the limiting mechanism includes a limiting plate, a limiting groove, and a plug rod. Limiting plates are fixed at both the front and rear ends of the vehicle body. The turntable has limiting grooves corresponding to pressing rollers one, two, three, and four. The limiting plate has slots of the same size as the limiting grooves. The limiting plate and the turntable are detachably connected by the plug rod. After selecting a pressing roller of appropriate width, the plug rod is inserted into the limiting plate and the turntable to prevent the turntable from rotating when pressing the pressing strip, thus improving the stability of use.

[0008] Furthermore, a limiting bolt that mates with the bottom side of the outrigger is screwed onto the screw rod. By screwing the limiting bolt onto the screw rod that mates with the bottom side of the outrigger, rotation of the screw rod is prevented during use.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a rotating turntable at the through groove of the vehicle body, and setting four pressing wheels of different widths (pressing wheel one, pressing wheel two, pressing wheel three, and pressing wheel four) around the turntable, the different widths of the joint pressing strips can be freely selected when pressing them together, avoiding the trouble of manually changing the pressing wheels, greatly reducing the labor intensity and improving work efficiency. By setting a counterweight on the vehicle body, a good pressing force is ensured for the joint pressing strips. By setting adjustable support legs and screws, it can be used for joint pressing strips of different depths. After selecting a pressing wheel of appropriate width, the insert rod is inserted into the limiting plate and the turntable to prevent the turntable from rotating when pressing the pressing strip, thus improving the stability of use. By screwing a limiting bolt that contacts the bottom of the support leg onto the screw, the screw is prevented from rotating during use. Attached Figure Description

A strip pressing wheel is rotatably connected to the inner side of each fixing seat 10 via a second rotating shaft 11. 12. Pressing rollers 17, 18, and 19 are provided. The width of pressing roller 12 is greater than that of pressing roller 2 17, the width of pressing roller 2 17 is greater than that of pressing roller 3 18, and the width of pressing roller 3 18 is greater than that of pressing roller 4 19. A limiting mechanism 9 is provided between the vehicle body 1 and the turntable 8. A rotating turntable 8 is provided at the through groove of the vehicle body 1, and four pressing rollers of different widths (12, 17, 18, and 19) are provided around the turntable 8. When pressing seam pressing strips of different widths, the rollers can be freely selected, avoiding the trouble of manually changing the pressing rollers, greatly reducing the labor intensity and improving the work efficiency. A counterweight 16 is provided on the vehicle body 1 to ensure good pressing force for the seam pressing strips. Adjustable support legs 2 and screws 3 are provided to accommodate seam pressing strips of different depths.

[0015] The limiting mechanism 9 includes a limiting plate 91, a limiting groove 92, and a plug rod 93. The limiting plates 91 are fixed at both the front and rear ends of the vehicle body 1.
