Description

Technical Field

[0001] The present application relates to the technical field of waterproof construction equipment, and more specifically, to a differential drive type waterproof coiled material paving robot. Background Art

[0002] In the field of modern building waterproof construction, high polymer modified asphalt waterproof coiled materials dominate. Before construction, these materials are in a rolled package. During the construction process, while the waterproof coiled material is being unrolled, the surface asphalt of the material needs to be melted and adhered to the waterproof base layer by compaction.

[0003] The prior art document with the publication number CN220285205U provides a differential drive type waterproof coiled material paving robot. By setting a vision module on the vehicle frame to collect the position of the marking line on the laid waterproof coiled material in real time, the control module controls the rotation speed of the drive motor corresponding to the drive wheel according to the position of the marking line, so that the vehicle frame returns to the correct position and travels in a straight line, ensuring that the waterproof coiled material is paved without wrinkles and the overlap width between waterproof coiled materials is more uniform and stable.

[0004] Although the above prior art solution can achieve the related beneficial effects through the structure of the prior art, the stability of the support for the waterproof coiled material of the above paving robot is not ideal, and there is a risk of the waterproof coiled material becoming loose. In view of this, we propose a differential drive type waterproof coiled material paving robot. Summary of the Invention

[0005] The purpose of the present utility model is to provide a differential drive type waterproof coiled material paving robot, which solves the technical problem that the poor stability of the support for the waterproof coiled material in the prior art causes the waterproof coiled material to be prone to looseness, and realizes the technical effects of reducing the difficulty of placing the waterproof coiled material and improving the stability of the waterproof coiled material.

[0006] The present utility model is realized through the following technical solutions:

[0007] A differential drive type waterproof coiled material paving robot, including a drive trolley and a support roller, and the support roller is used for supporting the waterproof coiled material;

[0008] The inside of the support roller is hollow, and a number of top blocks are slidably connected to the support roller;

[0009] A screwing block is rotatably connected to the support roller, a threaded rod is fixedly installed on the screwing block, and a push block is slidably connected inside the support roller, and the push block is in threaded cooperation with the threaded rod;

[0010] A slope is provided on the push block, and an adjusting block is fixedly connected to the top block.

[0011] By adopting the above technical solution, when the waterproof coiled material set is sleeved on the support roller through the inner lining, by rotating the screwing block, the threaded rod is driven to rotate. The threaded rod drives the push block to slide in the support roller through threaded transmission. The slope surface of the push block contacts and pushes the adjusting block out of the chute, fixing the inner lining of the waterproof coiled material from the inside and ensuring that the waterproof coiled material is stably fixed on the support roller.

[0012] As an alternative solution of the technical solution of this application document, a support rod and a number of elastic members are fixedly installed in the support roller. The elastic members correspond to the top block and the adjusting block one by one. One end of the elastic member is fixedly connected to the support rod, and the other end is fixedly connected to the top block and the adjusting block.

[0013] By adopting the above technical solution, when the push block disengages from the adjusting block, under the action of the elastic member, the top block can be quickly reset and slide into the support roller, reducing the difficulty of disassembling the inner lining from the support roller.

[0014] As an alternative solution of the technical solution of this application document, a sleeve is rotatably connected to one end of the support roller. A support shaft is fixedly installed on the sleeve. The support shaft is rotatably connected to the driving trolley. A control block is slidably connected to the driving trolley for limiting the support roller. A positioning pin is inserted into the driving trolley and the control block to fix the control block.

[0015] By adopting the above technical solution, there is a certain resistance to rotation between the sleeve and the support roller, preventing the support roller from freely rotating in the sleeve and causing the waterproof coiled material on the support roller to become loose.

[0016] As an alternative solution of the technical solution of this application document, a first half groove is formed on the driving trolley, and a second half groove is formed on the control block. The first half groove and the second half groove form a rotating shaft hole, and the support roller is rotationally matched with the rotating shaft hole.

[0017] By adopting the above technical solution, through the setting of the detachable control block, one end of the support roller can be rotated and opened, effectively reducing the difficulty of installing the waterproof coiled material and improving the installation efficiency. The support roller installed with the waterproof coiled material is rotationally buckled into the first half groove, and then the control block is slidably buckled on the other side of the first half groove, thereby effectively limiting the support roller and ensuring the stability during work.

[0018] As an alternative solution of the technical solution of this application document, it further includes a telescopic cylinder. The base of the telescopic cylinder is rotatably connected to the driving trolley. A connecting rod is rotatably connected to the driving trolley. One end of the connecting rod is rotatably connected to the output shaft of the telescopic cylinder, and the other end is rotatably installed with a pressure roller.

[0019] By adopting the above technical solution, through the setting of the pressure roller, the waterproof coiled material can be pressed tightly during laying, improving the laying effect. Beneficial effects

[0020] One or more technical solutions provided in the embodiments of the present application have the following technical effects or advantages:

[0021] 1. When the waterproof coiled material of the present application is sleeved on the support roller through the inner lining, by rotating the screwing block, the threaded rod rotates. The threaded rod drives the push block to slide in the support roller through threaded transmission. The slope surface of the push block contacts and pushes the adjusting block to slide out of the chute, fixing the inner lining of the waterproof coiled material from the inside, ensuring that the waterproof coiled material is stably fixed on the support roller.

[0022] 2. When the push block disengages from the adjusting block, under the action of the elastic member, the top block can be quickly reset and slide into the support roller, reducing the difficulty of disassembling the inner lining from the support roller.

[0023] 3. Through the setting of the detachable control block, one end of the support roller can be rotated and opened, effectively reducing the difficulty of installing the waterproof coiled material and improving the installation efficiency. The support roller installed with the waterproof coiled material is rotated and buckled into the first half groove, and then the control block is slid and buckled on the other side of the first half groove, thereby effectively limiting the support roller and ensuring the stability during work.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following further describes the present application in detail with reference to the accompanying drawings of the specification.

[0030] Refer to Figures 1 to 4, an embodiment of the present application discloses a differential drive type waterproof coiled material laying robot, including a driving cart 1 and a support roller 2. The support roller 2 is used for supporting the inner lining of the waterproof coiled material. The support roller 2 is hollow inside, and a plurality of sliding grooves 3 are opened on the support roller 2. A plurality of top blocks 4 are slidably connected in the sliding grooves 3. The top blocks 4 are used to tighten the inner lining of the waterproof coiled material. A screwing block 5 is rotatably connected to the support roller 2. A threaded rod 6 is fixedly installed on the screwing block 5. The threaded rod 6 is located inside the support roller 2 and is rotatably connected to the support roller 2. A pushing block 7 is slidably connected inside the support roller 2. The pushing block 7 is in threaded cooperation with the threaded rod 6. The pushing block 7 is provided with a slope, and an adjusting block 8 is fixedly connected to the top block 4. When the waterproof coiled material is sleeved on the support roller 2 through the inner lining, by rotating the screwing block 5 to drive the threaded rod 6 to rotate, the threaded rod 6 drives the pushing block 7 to slide inside the support roller 2 through threaded transmission. The slope of the pushing block 7 contacts and pushes the adjusting block 8 to slide out of the sliding groove 3, fixing the inner lining of the waterproof coiled material from the inside, and ensuring that the waterproof coiled material is stably fixed on the support roller 2.

[0031] A support rod 9 and a plurality of elastic members 10 are fixedly installed inside the support roller 2. The elastic members 10 correspond to the top blocks 4 and the adjusting blocks 8 one by one. One end of the elastic member 10 is fixedly connected to the support rod 9, and the other end is fixedly connected to the top block 4 and the adjusting block 8. When the pushing block 7 disengages from the adjusting block 8, under the action of the elastic member 10, the top block 4 can be quickly reset and slide into the support roller 2, reducing the difficulty of disassembling the inner lining from the support roller 2.

[0032] One end of the support roller 2 is rotatably connected to a sleeve 11. There is a certain resistance to rotation between the sleeve 11 and the support roller 2, avoiding the free rotation of the support roller 2 inside the sleeve 11 resulting in the loosening of the waterproof coiled material on the support roller 2. A support shaft 12 is fixedly installed on the sleeve 11. The support shaft 12 is rotatably connected to the driving cart 1. A first half groove 14 is opened on the driving cart 1. A control block 15 is slidably connected to the driving cart 1. A second half groove 16 is opened on the control block 15. The first half groove 14 and the second half groove 16 form a rotating shaft hole. The support roller 2 is rotationally matched with the rotating shaft hole. The control block 15 slides along the axis of the rotating shaft hole, and a positioning pin is inserted into the driving cart 1 and the control block 15 to fix the control block 15.

[0033] Through the setting of the detachable control block 15, one end of the support roller 2 can be rotated and opened, effectively reducing the difficulty of installing the waterproof coiled material and improving the installation efficiency. The support roller 2 installed with the waterproof coiled material is rotationally buckled into the first half groove 14, and then the control block 15 is slidably buckled on the other side of the first half groove 14, thereby effectively limiting the support roller 2 and ensuring the stability during work.

[0034] The robot further includes a telescopic cylinder 17. The base of the telescopic cylinder 17 is rotatably connected to the driving trolley 1. A connecting rod 18 is rotatably connected to the driving trolley 1. One end of the connecting rod 18 is rotatably connected to the output shaft of the telescopic cylinder 17, and the other end is rotatably installed with a pressure roller 19 for pressing during the laying of the waterproof coiled material to improve the laying effect.

[0035] The connecting shafts 112 on the two driving wheels 111 of the driving trolley 1 are interconnected through a differential 13, so as to realize the differential drive of the two driving wheels 111.

[0036] It should be noted that a driving motor can also be provided at one end of the supporting roller 2 and fixedly connected to the output shaft of the driving motor. The driving motor drives the supporting roller 2 to rotate synchronously with the driving wheel 111, so as to realize the unwinding of the waterproof coiled material, and the stability of the unwinding of the supporting roller 2 can be ensured.

[0037] When the differential drive type waterproof coiled material paving robot disclosed in the embodiment of the present application is in use, the positioning pin is removed and the control block 15 is slid to make one end of the supporting roller 2 in an open state. The supporting roller 2 on the open side is rotated around the supporting shaft 12, and the waterproof coiled material is sleeved on the supporting roller 2 through the inner lining. The supporting roller 2 is rotated and buckled into the first half groove 14, and then it is buckled on the other side of the first half groove 14 through the sliding control block 15 to limit the supporting roller 2. By rotating the screwing block 5 to drive the threaded rod 6 to rotate, the threaded rod 6 drives the push block 7 to slide in the supporting roller 2 through threaded transmission. The slope surface of the push block 7 contacts and pushes the adjusting block 8 to slide out of the chute 3, and the inner lining of the waterproof coiled material is fixed from the inside.
