Description

Technical Field

[0001] This utility model relates to a concrete backrest casting machine for curb stones, belonging to the technical field of road construction casting equipment. Background Technology

[0002] Before asphalt pavement construction, the curb stones are installed first. After installation, concrete backings are constructed to strengthen the structural strength of the curb stones. By adding concrete backings, the curb stones can be effectively protected from damage and their service life extended.

[0003] Because the outer concrete backing structure of the curbstone is a slender strip concrete component, traditional construction machinery cannot directly pour concrete onto it. Currently, there are some casting trolleys that use hoppers with discharge pipes at the bottom to guide concrete to the casting area between the backing template and the curbstone. However, the discharge pipes often get clogged during transport, and the pipes have bends at the ends. When moving the trolley, to prevent the bends from colliding with the curbstone, the bends must enter the casting area from one end of the curbstone, which is quite troublesome. Utility Model Content

[0004] This utility model provides a concrete backrest casting machine for curb stones, which solves the problem that the current discharge pipe often gets blocked during transportation, and the discharge pipe has an elbow structure at the end. When moving the trolley, in order to prevent the elbow part from hitting the curb stone, the elbow structure must enter the casting area from one end of the curb stone, which is quite troublesome.

[0005] This utility model relates to a concrete backrest casting and molding machine for curb stones, including a traveling trolley, a support column fixed to the top of the traveling trolley, a hopper installed on the support column, a screw conveyor fixed to the bottom of the hopper, an outlet at the outer end of the screw conveyor, a discharge bend connected to the outlet, a connecting ring plate fixed to the outer side of the outlet, a rotating ring plate fixed to the outer side of the top of the discharge bend, a rotating groove that mates with the rotating ring plate on the outer side of the connecting ring plate, a limiting plate that limits the rotating ring plate on the outer side of the connecting ring plate, the conveying auger of the screw conveyor extending into the discharge bend, positioning holes at the top and bottom of the rotating ring plate, an installation hole at the top of the connecting ring plate, and a limiting pin that mates with the positioning hole in the installation hole.

[0006] As a preferred embodiment, a support ring is fixed on the limiting pin on the inner side of the connecting ring plate, and a spring is sleeved on the limiting pin on the inner side of the support ring. The inner end of the spring is provided with a guide sleeve sleeved on the limiting pin, and a support rod is fixed on the outer side of the guide sleeve. The support rod is fixed on the connecting ring plate, which can better limit the connecting ring plate and the rotating ring plate and prevent the limiting pin from dislodging from the positioning hole.

[0007] As a preferred option, the inner end of the limiting pin is fixed with a pull rod, which makes it easy to pull the limiting pin.

[0008] As a preferred embodiment, a square limiting frame is fixed to the inner side of the support column, and a support flange is welded and fixed to the top of the support column on the outer side of the limiting frame. The hopper is located inside the limiting frame, and an L-shaped hanging plate is fixed to the outer wall of the hopper and hung on the support flange, which facilitates the installation and disassembly of the inner wall of the hopper for cleaning.

[0009] As an alternative, the front end of the traveling trolley near the discharge bend is also equipped with a guide mechanism for the trolley to move along the curb, which can better guide the traveling trolley and prevent it from going astray.

[0010] As a preferred embodiment, the guiding mechanism includes a horizontally arranged outer guide wheel and an inner guide wheel. Both the outer and inner guide wheels are rotatably mounted on a mounting bracket, which is fixedly connected to a hanger. The hanger of the inner guide wheel is fixed to the traveling trolley. By attaching the outer and inner guide wheels to the inner and outer sides of the curb stone respectively, it is easier to guide the traveling trolley.

[0011] As a preferred embodiment, a guide shaft is fixed to the top of the guide outer rubber wheel's suspension rod. An inner support sleeve is fitted over the guide shaft, and an outer support sleeve is fitted over the inner support sleeve. The outer end of the outer support sleeve is threadedly connected to a limiting cover plate that limits the inner support sleeve. A base frame is fixed to the bottom of the outer support sleeve and is mounted on a traveling trolley. A limiting disc is fixed to the inner end of the guide shaft through the outer support sleeve, and a spring is fitted onto the guide shaft inside the limiting disc. The guide shaft can move axially, allowing for an elastic allowance along the guide shaft's axis for the guide outer rubber wheel, preventing the guide outer and inner rubber wheels from getting stuck due to uneven curb installation.

[0012] As a preferred embodiment, the outer support sleeve is equipped with a limiting bolt, and the outer wall of the inner support sleeve has limiting threaded holes at both the top and bottom that mate with the limiting bolt. The inner sidewall of the inner support sleeve has a guide groove, and the outer sidewall of the guide shaft has a guide boss that mates with the guide groove. Before the traveling trolley moves to the pouring position, the limiting bolt can be rotated to disengage from the upper limiting threaded hole. Then, the guide shaft is rotated so that the outer guide wheel faces upward. At this point, the limiting bolt is screwed into the lower limiting threaded hole to prevent the outer guide wheel from colliding with the curb when the traveling trolley moves. After the traveling trolley moves into position and the inner guide wheel is pressed against the inner sidewall of the curb, the limiting bolt can be rotated to disengage from the lower limiting threaded hole. Then, the guide shaft is pulled outward and rotated so that the outer guide wheel faces downward. The guide shaft is then released, and the outer guide wheel rests against the outer sidewall of the curb.

[0013] This utility model has the following beneficial effects:

[0014] The concrete material in the hopper can be transported to the discharge bend by a screw conveyor to better prevent concrete blockage. The discharge bend and the outlet of the screw conveyor are equipped with a rotating and positioning structure. When the traveling trolley moves to the pouring position, the discharge bend can be rotated so that the outlet of the discharge bend faces upward, preventing the discharge bend from colliding with the curb when the traveling trolley moves. After the traveling trolley moves into position, the discharge bend is rotated back to face downward for pouring. Attached Figure Description

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Example 1, such as Figures 1 to 4 As shown, this utility model is a concrete backrest casting and molding machine for curb stones, including a traveling trolley 2. A support column 9 is fixed on the top of the traveling trolley 2. A hopper 10 is installed on the support column 9. A screw conveyor 3 is fixed on the bottom of the hopper 10. The outer end of the screw conveyor 3 is provided with an outlet. A discharge bend 6 is connected to the outlet. A connecting ring plate 8 is fixed on the outer side of the outlet. A rotating ring plate 17 is fixed on the outer side of the top of the discharge bend 6. A rotating groove that cooperates with the rotating ring plate 17 is provided on the outer side of the connecting ring plate 8. A limiting plate that limits the rotating ring plate 17 is provided on the outer side of the connecting ring plate 8. The conveying auger 7 of the screw conveyor 3 extends into the discharge bend 6. The top and bottom of the rotating ring plate 17 are provided with positioning holes. The top of the connecting ring plate 8 is provided with an installation hole. A limiting pin 14 that cooperates with the positioning hole is provided in the installation hole.

[0022] Construction workers move the trolley 2 to the concrete transport truck, put concrete into the hopper 10, and then pull the limiting pin 14 inward to disengage it from the top positioning hole. They then rotate the discharge bend 6 so that its outlet faces upward, and insert the limiting pin 14 into the bottom positioning hole. Next, they move the trolley 2 to the edge of the road surface 1, positioning the discharge bend 6 between the curbstone 5 and the arranged backrest template 4. They then pull the limiting pin 14 inward to disengage it from the bottom positioning hole, rotate the discharge bend 6 so that its outlet faces downward, and insert the limiting pin 14 into the top positioning hole. The screw conveyor 3 is then started to transport the concrete in the hopper 10 to the outlet of the discharge bend 6. The trolley 2 is controlled to move along the edge of the road surface 1 in the pouring direction, thus quickly and efficiently completing the pouring of the concrete backrest of the curbstone 5.

[0023] In Example 2, based on Example 1, a support ring 13 is fixed on the limiting pin 14 on the inner side of the connecting ring plate 8. A spring 16 is sleeved on the limiting pin 14 on the inner side of the support ring 13. The inner end of the spring 16 is provided with a guide sleeve 15 sleeved on the limiting pin 14. A support rod is fixed on the outer side of the guide sleeve 15 and the support rod is fixed on the connecting ring plate 8.

[0024] A pull rod is fixed to the inner end of the limiting pin 14. Before rotating the discharge bend 6, hold the pull rod with your hand and pull the limiting pin 14 inward so that the limiting pin 14 overcomes the elastic force of the spring-16 and disengages from the positioning hole. Then the discharge bend 6 can be rotated. After the discharge bend 6 is rotated into place, release the pull rod. The limiting pin 14 will be inserted into the positioning hole under the elastic force of the spring-16.

[0025] A square limiting frame 11 is fixed to the inner side of the support column 9. A supporting flange is welded and fixed to the top of the support column 9 on the outer side of the top of the limiting frame 11. The hopper 10 is located inside the limiting frame 11. An L-shaped hanging plate 12 is fixed on the outer wall of the hopper 10 and hung on the supporting flange.

[0026] The front end of the traveling trolley 2 is also equipped with a guide mechanism for the trolley to move along the curbstone 5 near the discharge bend 6.

[0027] The guiding mechanism includes a horizontally arranged outer guide wheel 18 and an inner guide wheel. Both the inner guide wheel and the outer guide wheel 18 are rotatably mounted on a mounting frame. The mounting frame is fixedly connected to a hanger rod. The hanger rod of the inner guide wheel is fixed on the traveling trolley 2.

[0028] A guide shaft 20 is fixed to the top of the rod of the guide outer rubber wheel 18. A support inner sleeve 21 is fitted on the outside of the guide shaft 20. A support outer sleeve 22 is fitted on the outside of the support inner sleeve 21. The outer end of the support outer sleeve 22 is threadedly connected to the limiting cover plate 19 of the limiting support inner sleeve 21. A base frame is fixed to the bottom of the support outer sleeve 22. The base frame is fixed on the traveling trolley 2. The inner end of the guide shaft 20 passes through the support outer sleeve 22 and is fixed to a limiting plate 26. A spring 25 is provided on the inner side of the limiting plate 26 and is fitted on the guide shaft 20.

[0029] The outer sleeve 22 is provided with a limiting bolt 23, and the outer wall of the inner sleeve 21 is provided with limiting threaded holes that cooperate with the limiting bolt 23 on both the top and bottom. The inner side wall of the inner sleeve 21 is provided with a guide groove, and the outer side wall of the guide shaft 20 is provided with a guide boss 24 that cooperates with the guide groove. Before the trolley 2 moves to the pouring position, the limiting bolt 23 can be rotated to disengage it from the upper limiting threaded hole. Then, the guide shaft 20 is rotated so that the outer guide wheel 18 faces upward. At this time, the limiting bolt 23 is screwed into the lower limiting threaded hole to prevent the outer guide wheel 18 from colliding with the curbstone 5 when the trolley 2 moves to the pouring position. After the trolley 2 moves into position, the inner guide wheel is pressed against the inner wall of the curbstone 5. The limiting bolt 23 can then be rotated to disengage it from the lower limiting threaded hole. Then, the guide shaft 20 is pulled outward and rotated so that the outer guide wheel 18 faces downward. The guide shaft 20 is then released, and the outer guide wheel 18 is pressed against the outer wall of the curbstone 5. The trolley 2 can then be pushed forward along the edge of the road surface 1 in the pouring direction. Even if there is a problem with the straightness of the curbstone 5, the axial elastic movement of the guide shaft 20 will prevent jamming.
