Description

Technical Field

[0001] This utility model relates to the technical field of mobile crushing and screening equipment, specifically to a conveyor belt conveyor that is easy to move and adjust in position. Background Technology

[0002] Mobile crushing and screening equipment, characterized by its integrated unit, flexibility, and on-site modularity, is increasingly favored by customers. For example, tracked mobile cone crushers are generally used for intermediate crushing to produce medium-grade products. Existing tracked mobile cone crushers typically integrate screen boxes for preliminary screening of crushed materials. To facilitate the smooth transfer of large materials from the screen box to the discharge or return conveyor belts, a transfer conveyor belt is usually installed. This allows the large materials to first fall onto the transfer conveyor belt and then be transported to the discharge or return conveyor belt. However, since existing transfer conveyors are usually directly fixed to the equipment frame, actual on-site use has revealed that when the conveyor belts wear out due to prolonged use and need replacement, the fixed and non-adjustable installation position of the conveyor belt, coupled with the compact overall equipment, leaves insufficient space for maintenance personnel to access and perform maintenance operations. This makes belt replacement troublesome, difficult, time-consuming, and labor-intensive. Therefore, this problem has been studied, leading to this case study. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a conveyor belt that allows the installation position of the conveyor belt body to be non-fixed and adjustable, which facilitates movement and switching between working position and maintenance position, can form sufficient maintenance space during maintenance, and makes belt replacement easier, simpler and more time-saving.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a transfer belt conveyor that is easy to move and adjust, including a transfer belt conveyor body, a movable support limiting device, and a locking and fixing device. The transfer belt conveyor body is movablely supported on the movable support limiting device and can move and switch between a maintenance position when it extends outward and a working position when it retracts inward. The movable support limiting device can also limit the left and right sides of the transfer belt conveyor body when it moves. The movable support limiting device is fixedly installed on the equipment frame. The locking and fixing device is installed between the movable support limiting device and the transfer belt conveyor body and is used to keep the transfer belt conveyor body stably in the maintenance position or the working position.

[0005] Furthermore, the movable support limiting device includes a support frame and support rollers. The support frame is fixedly connected to the equipment frame. Multiple rotatable support rollers are installed on both the left and right sides of the upper end of the support frame. The multiple support rollers are spaced apart along the moving direction of the conveyor belt body. The left and right sides of the lower end of the conveyor frame of the conveyor belt body respectively abut against and are supported on the multiple support rollers on the left and right sides of the support frame.

[0006] Furthermore, the support frame includes two parallel and spaced-apart support seats, each support seat includes two parallel and spaced-apart support plates, and support rollers are disposed between the two support plates.

[0007] Furthermore, the support plate has multiple spaced rotating holes along its length. The support roller is rotatably mounted on the pin. The pin is detachably inserted into the corresponding rotating holes on the two support plates. The end of the pin is fitted with a washer and is detachably inserted with a cotter pin.

[0008] Furthermore, an annular limiting plate is fixed on the edge of the end face of the support roller away from the main body of the conveyor belt, and a moving limiting groove is formed between the annular limiting plates on the support rollers on the left and right sides of the upper end of the support frame to limit the movement of the main body of the conveyor belt.

[0009] Furthermore, at least three support rollers are provided on both the left and right sides of the upper end of the support frame.

[0010] Furthermore, multiple locking and fixing devices are provided on both the left and right sides between the movable support limiting device and the main body of the transfer belt conveyor. The locking and fixing devices include locking pressure plates, fixing plates, and locking bolt assemblies. The fixing plates are fixed on the belt conveyor frame of the main body of the transfer belt conveyor. The fixing plates are provided with pressure holes. The locking pressure plates are bent at right angles. One end of the locking pressure plates is fixed with a pressure block that matches the pressure hole. The pressure block can be detachably locked in the pressure hole. The other end of the locking pressure plates is detachably connected to the support frame through the locking bolt assembly.

[0011] Furthermore, the locking bolt assembly consists of multiple bolts spaced apart. Each locking bolt assembly includes a locking bolt and a locking nut. The locking plate has a fixing hole, and the support frame has a locking hole. The locking bolt passes through the fixing hole and the locking hole in sequence and is threadedly connected to the locking nut. The locking nut is fixedly mounted on the support frame.

[0012] Furthermore, the locking holes are elongated and arranged vertically, while the pressing holes are elongated and arranged horizontally.

[0013] Furthermore, at least three locking devices are provided on both the left and right sides between the movable support limiting device and the main body of the transfer belt conveyor.

[0014] As described above, the conveyor belt provided by this utility model, which is easy to move and adjust, has the following beneficial effects: By setting a movable support limiting device, the conveyor belt body can be easily moved and switched within the movable support limiting device, thus making the installation position of the conveyor belt body not fixed and adjustable. When the equipment needs to work, the conveyor belt body can be moved and switched to the inward retracted working position, and locked and fixed by the locking and fixing device, thereby stabilizing it in the working position. When the conveyor belt body needs to be repaired or its belt replaced, the conveyor belt body can be moved and switched to the outward extended maintenance position, and locked and fixed by the locking and fixing device, thereby stabilizing it in the maintenance position. At this time, one end of the conveyor belt body can extend a certain distance outward from the equipment frame, and the center of gravity of the conveyor belt body is still on the movable support limiting device, thus forming sufficient maintenance space to facilitate maintenance personnel to perform maintenance operations and replace the conveyor belt body, making belt replacement easier, simpler, and more time-saving and labor-saving.

Detailed Implementation

[0025] The present invention will be further described below through specific embodiments.

[0026] like Figures 1 to 9 As shown, the present invention provides a conveyor belt that is easy to move and adjust, comprising a conveyor belt body 1, a movable support limiting device 2, and a locking and fixing device 3. The conveyor belt body 1 is movably supported on the movable support limiting device 2 and can move and switch between a maintenance position when extended outward and a working position when retracted inward. The movable support limiting device 2 can also limit the left and right sides of the conveyor belt body 1 when it moves. The movable support limiting device 2 is fixedly mounted on the equipment frame 4. The locking and fixing device 3 is located between the movable support limiting device 2 and the conveyor belt body 1 and is used to keep the conveyor belt body 1 stably in the maintenance position or the working position.

[0027] The movable support limiting device 2 facilitates the movement and switching of the conveyor belt body 1, making its installation position non-fixed and adjustable. When the equipment needs to operate, the conveyor belt body 1 can be moved to the inward retracted working position, and locked in place by the locking and fixing device 3, thus ensuring its stable position. When maintenance or belt replacement is required, the conveyor belt body 1 can be moved to the inward retracted working position. The main body 1 moves to the maintenance position when it extends outward, and the locking and fixing device 3 locks and fixes the main body 1 of the conveyor belt, so that it is stably in the maintenance position. At this time, one end of the head of the conveyor belt 1 can extend outward from the equipment frame 4 by a certain distance, and the center of gravity of the conveyor belt 1 is still on the moving support limiting device 2, thus forming sufficient maintenance space to facilitate maintenance personnel to perform maintenance operations and replace the belt of the conveyor belt 1. This makes belt replacement easier, simpler, and saves time and effort.

[0028] The movable support limiting device 2 includes a support frame 21 and support rollers 22. The support frame 21 is fixedly connected to the equipment frame 4. Multiple rotatable support rollers 22 are installed on the left and right sides of the upper end of the support frame 21. The multiple support rollers 22 are spaced apart along the moving direction of the conveyor belt body 1. The left and right sides of the lower end of the conveyor frame 11 of the conveyor belt body 1 abut against and are supported on the multiple support rollers 22 on the left and right sides of the support frame 21, respectively. In this way, the conveyor belt body 1 can be stably supported on the multiple support rollers 22 by utilizing its own weight. At the same time, the rolling of the support rollers 22 makes it easy for the operator to push the conveyor belt body 1 to move.

[0029] The support frame 21 includes two parallel and spaced support seats 211, and each support seat 211 includes two parallel and spaced support plates 2111. The support roller 22 is located between the two support plates 2111. Preferably, the support plates 2111 are unequal angle steel, which has good overall structural strength and can provide stable support.

[0030] Correspondingly, the support plate 2111 is provided with a plurality of spaced rotating holes 2112 along its length direction. The support roller 22 is rotatably mounted on the pin 23. The pin 23 is detachably inserted into the corresponding rotating holes 2112 on two of the support plates 2111. The end of the pin 23 is fitted with a washer 24 and is detachably inserted with a cotter pin 25. This facilitates the rotatable mounting of the support roller 22 on the support frame 21, and its installation is simple and its structure is stable.

[0031] An annular limiting plate 221 is fixedly provided on the support roller 22 at the edge of the end face away from the transfer conveyor body 1. A moving limiting groove is formed between the annular limiting plates 221 on the support roller 22 on the left and right sides of the upper end of the support frame 21 to limit the movement of the transfer conveyor body 1. At the same time, it can also guide the movement of the transfer conveyor body 1 and effectively prevent the transfer conveyor body 1 from accidentally falling off from the left and right sides when moving.

[0032] Preferably, at least three support rollers 22 are provided on both the left and right sides of the upper end of the support frame 21, thereby ensuring that when the conveyor belt body 1 is in the maintenance position, at least two support rollers 22 on both the left and right sides of the support frame 21 support the conveyor belt body 1.

[0033] Multiple locking and fixing devices 3 are provided on both the left and right sides between the movable support limiting device 2 and the conveyor belt body 1. Each locking and fixing device 3 includes a locking pressure plate 31, a fixing plate 32, and a locking bolt assembly 33. The fixing plate 32 is fixedly mounted on the conveyor frame 11 of the conveyor belt body 1. The fixing plate 32 has a pressure hole 321. The locking pressure plate 31 is bent at a right angle. One end of the locking pressure plate 31 is fixedly provided with a pressure block 311 that matches the pressure hole 321. The pressure block 311 is detachably locked into the pressure hole 321. The other end of the locking pressure plate 31 is detachably connected to the support frame 21 via the locking bolt assembly 33. Therefore, the conveyor belt body 1 can be limited and fixed in the front-back and vertical directions, and its position can be controlled accordingly. When the conveyor belt body 1 needs to be moved and switched between the maintenance position and the working position, it is first possible to loosen the locking bolt assembly 33 from the locking plate 31. At this time, the locking plate 31 can be removed and the pressure block 311 can be disengaged from the pressure hole 321, thereby releasing the locking of the conveyor belt body 1. Then, the operator can move the conveyor belt body 1 to the maintenance position or the working position. Finally, the pressure block 311 on the locking plate 31 is reinserted into the corresponding pressure hole 321, and the locking bolt assembly 33 is used to lock the locking plate 31. This ensures that the conveyor belt body 1 is stably positioned in the maintenance position or the working position.

[0034] Preferably, there are multiple locking bolt assemblies 33 arranged at intervals. Each locking bolt assembly 33 includes a locking bolt and a locking nut. The locking pressure plate 31 has a fixing hole 312, and the support frame 21 has a locking hole 2113. The locking bolt passes through the fixing hole 312 and the locking hole 2113 in sequence and is threadedly connected to the locking nut. The locking nut is fixedly mounted on the support frame 21. Preferably, there are 2-3 locking bolt assemblies 33, which facilitates locking the locking pressure plate 31 onto the support frame 21.

[0035] Preferably, the locking hole 2113 is elongated and arranged vertically, and the pressing hole 321 is elongated and arranged horizontally.

[0036] Preferably, at least three locking devices 3 are provided on both the left and right sides of the movable support limiting device 2 and the transfer belt conveyor body 1, thereby ensuring that when the transfer belt conveyor body 1 is in the maintenance position, at least two locking devices 3 on both the left and right sides of the support frame 21 lock and fix the transfer belt conveyor body 1.

[0037] The above are only some specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
