Description

Technical Field

[0001] This utility model relates to the field of equipment for disassembling and installing pressure roller bearing housings, and in particular to a roller bearing housing transport vehicle. Background Technology

[0002] The bearing housing of a rolling mill roll supports the roll and enables its rotation. Therefore, it is large and heavy, making the disassembly and assembly of the bearing housing to the roll a challenging task in the industry when the roll needs to be replaced. Traditional disassembly and assembly processes require transporting the bearing housing and aligning it with the roll, making hoisting methods impractical.

[0003] Although the applicant's patent CN 222944201 U discloses a device for disassembling and assembling a flat-head sleeve, it simultaneously solves the problems of transportation and alignment, and therefore can be referenced. However, in practical applications, the flat-head sleeve only exists at one end of the roller, so only one transport vehicle is needed. But the bearing housing exists at both ends of the roller, requiring simultaneous transportation and alignment during disassembly and assembly, thus necessitating two transport vehicles. However, using the patented solution with two transport vehicles presents space limitations, therefore, improvements are needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to design a roller bearing housing transportation device. This transportation vehicle solves the problems of transporting double bearing housings and aligning them with the rollers, while also saving space. It is suitable for the simultaneous disassembly and installation of double bearing housings.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a roller bearing seat transport device, comprising a hollow foundation, a hydraulic station set at one end of the foundation, the hydraulic station being connected to multiple hydraulic pipelines, the output end of the hydraulic pipelines being connected to a cylinder assembly, the cylinder assembly comprising two cylinders arranged in opposite directions, the cylinders being fixed on a cylinder bracket, the end of the piston rod of each cylinder being connected to a transport trolley, the front and rear ends of the transport trolley being respectively provided with follower cover plates, the two ends of the follower cover plates being connected to follower cover plate tracks, the follower cover plate tracks being set on the inner side of the foundation.

[0006] Furthermore, the follower cover plate includes a follower cover plate head plate and a rear follower cover plate, wherein the follower cover plate head plate is fixedly connected to the transport trolley.

[0007] Furthermore, a clamping component is fixedly connected to the body of the follower cover head plate, and the clamping component is fixedly connected to the transport trolley.

[0008] Furthermore, the end of the head plate of the follower cover is connected to the end of the rear follower cover by a connecting plate.

[0009] Furthermore, the inner sidewall of the foundation 1 is provided with multiple steps, and the follower cover plate track is fixed on the steps.

[0010] Furthermore, the follow-up cover track includes a track body and several fixing blocks fixed to one side of the track body, and the fixing blocks are fixedly connected to the step.

[0011] Furthermore, the track body includes a front bend, a middle straight section, and a rear bend.

[0012] Furthermore, the bending angle of the front end bend is 180°, and the bending angle of the tail end bend is [missing value].

[0013] Furthermore, a movable cover plate track is provided at the upper end of the front bending section.

[0014] Furthermore, the transport trolley is equipped with a hydraulic cylinder, the upper end of which is connected to the trolley lifting plate, and the output end of the hydraulic pipeline is connected to the hydraulic cylinder.

[0015] Beneficial effects: By setting follow-up covers at the front and rear ends of the transport trolley, the follow-up covers can cover the trolley as it moves back and forth, making the transport process safer and more aesthetically pleasing. In addition, the design of the follow-up covers bending along the track can save operating distance, thereby preventing the bearing seats and rollers from not aligning due to the large distance when two transport trolleys move towards each other.

[0016] A sliding cover track is installed on the follower cover track. When needed, the sliding cover can be placed on top of the follower cover to prevent dust and other debris from soiling the sliding cover and to facilitate cleaning. Attached Figure Description

Detailed Implementation

[0026] To enhance understanding of this utility model, it will be described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0027] like Figure 1-3 The image shows a roller bearing housing transport device, which includes a hollow foundation 1. Multiple steps 11 are provided on the inner wall of the foundation 1 for installing and placing accessories. A hydraulic station 2 is provided at one end of the foundation 1, and the hydraulic station 2 is connected to multiple hydraulic pipelines 3.

[0028] The output ends of multiple hydraulic lines 3 extend into the interior of the foundation 1 and are connected to different hydraulic cylinders located inside the foundation 1.

[0029] Specifically, such as Figure 4 As shown, the hydraulic line 3 is connected to the cylinder assembly 4 that controls the forward and backward movement of the transport trolley 5. Since the bearing seats to be disassembled and assembled in this application are two located at both ends of the roller, the transport trolley 5 consists of two trolleys arranged opposite to each other. Therefore, the cylinder assembly 4 includes two cylinders 41 arranged in opposite directions, and both cylinders 41 are fixed on the cylinder bracket 42.

[0030] The piston rod 411 of the hydraulic cylinder 41 is connected to the transport trolley 5 and is used to control the forward and backward movement of the transport trolley 5.

[0031] The rollers of the transport trolley 5 are on the side, so its track is set on the inner side wall of the foundation 1 and fixedly connected to the side of the inner side wall step.

[0032] Follower cover plates 6 are respectively installed at the front and rear ends of the transport trolley 5. The two ends of the follower cover plate 6 are connected to the follower cover plate track 7, and the follower cover plate track 7 is fixed on the step on the inner side wall of the foundation 1.

[0033] Specifically, such as Figure 5-7As shown, the follower cover 6 includes a follower cover head plate 61 and a rear follower cover 62. The follower cover head plate 61 is the follower cover that is close to the front and rear ends of the transport trolley 5. A clamping component 611 is fixedly connected to its body, and the clamping component 611 is detachably connected to the transport trolley 5. The rear follower cover 62 is placed sequentially on the side of the follower cover head plate 61 away from the transport trolley, and the follower cover 6 is sequentially connected by connecting plates 63 located at both ends of the follower cover 6.

[0034] Follow-up cover track such as Figure 8 As shown, it includes a track body 71 and a fixing block 72 arranged along the length of the track body 71. The fixing block 72 is fixedly connected to the steps of the foundation 1.

[0035] The track body 71 includes a front bend 711, a middle straight section 712, and a rear bend 713. The bending angle of the front bend 711 is 180°, and the bending angle of the rear bend 713 is 90°.

[0036] When the transport trolley 5 moves forward, it pushes the follower cover 6 forward. After passing the straight section 712, it reaches the front bending section 711. At this time, since the bending angle of the front bending section 711 is 180°, the follower cover 6 turns and moves inward. This design saves space.

[0037] Similarly, when the transport trolley 5 moves backward, it pushes the follower cover 6 to move backward, passing through the straight section 712 and reaching the tail bend section 713. Since the tail bend section 713 is designed to be vertical at 90°, the follower cover 6 turns downward, which also saves space.

[0038] It should be noted that the purpose of the movable cover is to cover the front and rear of the transport trolley, both for safety and aesthetics. Traditional designs use movable covers, but these covers cannot be bent, resulting in a large space requirement. Furthermore, when the two transport trolleys move relative to each other, the distance between the endpoints becomes too great, making it impossible to disassemble or assemble the bearing housing.

[0039] The design of the bendable follow-up cover plate of this application solves the above-mentioned space limitation problem.

[0040] The follow-up cover track 7 can also be connected to the movable cover track 73, and the movable cover can be placed in the movable cover track 73 to cover the follow-up cover 6, making it convenient to clean dust and other debris.

[0041] According to a preferred embodiment of the present invention, a hydraulic cylinder is installed on the transport trolley, the end of the hydraulic pipeline 3 is connected to the cylinder, and the upper part of the transport trolley is connected to the cylinder, thereby realizing the up and down movement of the transport trolley.

[0042] According to a preferred embodiment of the present invention, a disassembly and assembly workbench that can move up and down is set between two transport trolleys to place rollers. The end of the hydraulic line 3 is connected to the oil cylinder of this workbench to control the up and down movement of the disassembly and assembly workbench.

[0043] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
