Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: an inner wall polishing device for processing steel bar sleeves, comprising a processing box 1, an electric lifting rod 3 fixedly installed on the top of the processing box 1, a lifting box 4 fixedly installed below the electric lifting rod 3, sliding rods 2 fixedly installed above the lifting box 4 and on both sides of the electric lifting rod 3, a motor 10 fixedly installed inside the lifting box 4, a grinding disc assembly 5 fixedly installed below the output end of the motor 10, two clamping plates 6 provided inside the processing box 1 and below the grinding disc assembly 5, the processing box 1 and the two clamping plates 6 being connected by two first electric telescopic rods 7, a collection support device 8 fixedly installed below the processing box 1, and a storage lighting device 9 provided on one side of the lifting box 4.

[0023] Specifically, the collection support device 8 includes a filter cloth 81, a support assembly 82, a fan 83, a collection box 85, a support frame 86, and a fixing net 87. The support frame 86 is fixedly installed at the bottom of the processing box 1, the fixing net 87 is fixedly installed at the top of the support frame 86, the collection box 85 is provided on the inner side of the support frame 86, the filter cloth 81 is fixedly installed at the bottom of the collection box 85, multiple fans 83 are fixedly installed at the bottom of the support frame 86, and the support assembly 82 is fixedly installed at the bottom of the support frame 86 and on both sides of the multiple fans 83.

[0024] By adopting the above technical solution, workers can collect and treat the dust generated during polishing when needed through the cooperation of structures such as the fan 83 and the collection box 85, thereby reducing the difficulty of dust cleaning and better meeting the needs of the work.

[0025] Specifically, the collection support device 8 also includes spring pins 84, and the support frame 86 and the collection box 85 are connected by two spring pins 84.

[0026] By adopting the above technical solution, the staff can connect or separate the support frame 86 and the collection box 85 through two spring pins 84 when needed, which facilitates the loading and unloading of the collection box 85.

[0027] Specifically, the support assembly 82 includes a support frame 821, a screw 822, and a connecting frame 823. The connecting frame 823 is fixedly installed below the support frame 86 and on both sides of the multiple fans 83. Multiple support frames 821 are provided on the outside of the connecting frame 823. The screw 822 is installed on the inside of the support frame 821 and on the bottom inside of the connecting frame 823 via a bearing.

[0028] By adopting the above technical solution, workers can use the cooperation of structures such as screw 822 and support frame 821 to keep the device stable on uneven ground when needed, thereby reducing the possibility of adverse effects on work.

[0029] In this embodiment, when the device is used to polish the inner wall of the rebar sleeve, if the device is on an uneven surface, the operator can rotate the screws 822 in the two support components 82 of the collection support device 8 according to the ground conditions. The screws 822 are connected to the support frame 821 by bearings, and the screws 822 are connected to the connecting frame 823 by threads. The inner side of the support frame 821 and one side of the connecting frame 823 are in contact with each other. Therefore, each screw 822 drives each support frame 821 to rise and fall, thereby adapting to the ground conditions and ensuring the stability of the device. Then, the operator opens the processing box 1, places the rebar sleeve between the two clamping plates 6 above the fixing net 87, and activates the two first electric telescopic rods 7 to move the two clamping plates 6, thereby clamping and fixing the rebar sleeve. The motor 10 inside the lifting box 4 drives the grinding disc assembly 5 to rotate. The electric lifting rod 3 is activated, causing the lifting box 4 and slide rod 2 to descend, thereby driving the rotating grinding disc assembly 5 into the inner side of the rebar sleeve to polish the inner wall of the rebar sleeve. During this process, the operator can activate each fan 83. Under the action of each fan 83, the dust generated during polishing passes through the fixed net 87 and enters the collection box 85. The dust is then blocked by the filter cloth 81, thus collecting and treating the dust. After polishing is completed, the electric lifting rod 3 is activated to drive the grinding disc assembly 5 and other structures back to their original height. The motor 10 and each fan 83 are then turned off. After the work is completed, the operator can manipulate the two spring pins 84 on the support frame 86 when needed to detach it from the collection box 85, and then remove the collection box 85 and the dust inside.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the storage lighting device 9 includes a storage box 91, a layered plate 95 and a door panel 96. The storage box 91 is fixedly installed on one side of the processing box 1 near the edge and on the side of the lifting box 4. The door panel 96 is installed on the side of the storage box 91 away from the lifting box 4 via a hinge. Two layered plates 95 are fixedly installed on the inner side of the storage box 91.

[0032] By adopting the above technical solution, workers can temporarily store the steel bar sleeves when needed through the cooperation of the storage box 91 and the door panel 96, thereby better meeting the work needs in different situations.

[0033] Specifically, the storage lighting device 9 also includes a second electric telescopic rod 92, a lighting lamp 93, and a transparent box 94. The second electric telescopic rod 92 is fixedly installed on the side of the storage box 91 near the lifting box 4. The transparent box 94 is fixedly connected to the bottom of the second electric telescopic rod 92. The lighting lamp 93 is fixedly installed on the inside of the transparent box 94.

[0034] By adopting the above technical solution, the staff can provide auxiliary lighting inside the processing box 1 when the light is insufficient, which makes it easier for the staff to observe the condition of the steel bar sleeve and better meet the needs of the work.

[0035] In this embodiment, when it is necessary to store the rebar sleeves, the worker can open the door panel 96 in the storage lighting device 9, place the rebar sleeves in the storage box 91, and the layering plate 95 serves to separate the layers. Then, the door panel 96 can be closed. When the light is insufficient, the worker can turn on the light 93 in the transparent box 94 to illuminate the processing box 1. The worker can also activate the second electric telescopic rod 92 to raise and lower the transparent box 94 and the light 93 inside, thereby adjusting the lighting position.

[0036] The structure and principle of the processing box 1 and the grinding disc assembly 5, which consists of a rotating rod, a grinding disc, an auxiliary mechanism, a pressing ring, a rotating cylinder, a support plate, a positioning rod, a pulling plate, a spring, a fixing plate, and a fixing rod, have been disclosed in Chinese Patent Application No. 202420947307.1, which discloses an inner wall polishing device for processing steel bar sleeves. Its working principle is as follows: during use, pulling the fixing block causes the operating plate to move, which in turn causes the limiting rod to move, disengaging it from the connecting rod. This releases the position restriction on the connecting rod. Then, the grinding disc is pulled horizontally, causing it to move the connecting rod, disengaging it from the fixing cylinder. This allows for the disassembly of the connecting rod and the grinding disc, and then replacement with a connecting rod of the appropriate length for continued use.

[0037] The working principle and usage process of this utility model are as follows: When the device is needed to polish the inner wall of a rebar sleeve, if the device is on an uneven surface, the operator can rotate the screws 822 in the two support components 82 of the collection support device 8 according to the ground conditions. The screws 822 are connected to the support frame 821 by bearings, and the screws 822 are connected to the connecting frame 823 by threads. The inner side of the support frame 821 and one side of the connecting frame 823 are in contact with each other. Therefore, each screw 822 drives each support frame 821 to rise and fall, thereby adapting to the ground conditions and ensuring the stability of the device. Then, the operator opens the processing box 1, places the rebar sleeve between the two clamping plates 6 above the fixing net 87, and starts the two first electric telescopic rods 7 to move the two clamping plates 6, thereby clamping and fixing the rebar sleeve. Then, the motor 10 in the lifting box 4 is started, thereby driving the grinding disc assembly 5 to rotate. The electric lifting rod 3 is started to drive the lifting box 4 and the sliding rod 2 and other structures to descend, thereby driving the rotating grinding disc assembly 5 into the inner side of the rebar sleeve, thereby polishing the inner wall of the rebar sleeve. The inner wall of the rebar sleeve is polished. During this process, the operator can start each fan 83. Under the action of each fan 83, the dust generated during polishing passes through the fixed net 87 and enters the collection box 85. Then the dust is blocked by the filter cloth 81, thus collecting and treating the dust. After polishing is completed, the electric lifting rod 3 is started to drive the grinding disc assembly 5 and other structures back to their original height. The motor 10 and each fan 83 are turned off. After the work is completed, the operator can manipulate the two spring pins 84 on the support frame 86 to disengage it from the collection box 85 when needed, and then take out the collection box 85 and the dust inside. When it is necessary to store the rebar sleeve, the operator can open the door panel 96 in the storage lighting device 9, place the rebar sleeve in the storage box 91, and the layering plate 95 plays a layering role. Then the door panel 96 can be closed. When the light is insufficient, the operator can turn on the light 93 in the transparent box 94 to illuminate the processing box 1. The operator can also start the second electric telescopic rod 92 to raise and lower the transparent box 94 and the light 93 inside, thereby adjusting the lighting position.
