Description

Technical Field

[0001] This utility model relates to the field of idler roller replacement tools, and specifically discloses an idler roller quick replacement support device. Background Technology

[0002] Belt conveyors typically weigh over 50 kg / m, and the idler rollers themselves weigh around 5 kg. Due to the lack of available auxiliary support tools, workers must manually lift and carry the idler rollers for disassembly, installation, and replacement. In confined spaces or areas with heavy belts, chain hoists are needed to lift the conveyor before operation, generally requiring 3-4 people working simultaneously. This is extremely labor-intensive, inefficient, and prone to accidents, posing significant safety hazards and operational risks. Therefore, quick-change idler roller support devices are now used to support the belt, enabling rapid idler roller replacement.

[0003] The existing support device uses turnbuckles and cross brackets to support the belt. The cross brackets are mostly planar supports and lack limit design. When supporting, the cross bracket is prone to side slip when it comes into contact with the belt. Moreover, the metal contact surface without buffer and anti-slip measures has a low coefficient of friction. Under load fluctuation or vibration conditions, the cross bracket will be displaced, resulting in low stability and safety hazards. Utility Model Content

[0004] This utility model proposes a quick-change support device for idler rollers. The limiting hooks play a limiting role to prevent the cross top frame from slipping sideways. At the same time, the base and channel steel form a stable support surface, which can stably support the belt and facilitate workers to quickly change the idler rollers under the belt.

[0005] This utility model is implemented as follows: a quick-change support device for idler rollers includes a turnbuckle, two symmetrically distributed screws connected to the internal thread of the turnbuckle, a connecting ring fixed to the top of the top screw, and a bottom support mechanism and a top support mechanism respectively provided at the relatively far ends of the two screws.

[0006] The bottom support mechanism includes a channel steel fixedly connected to a screw located below. A base is welded and fixed to the bottom of the channel steel. The base includes two semi-circular and symmetrically distributed base plates. An angle steel is welded and fixed between the two base plates.

[0007] The top support mechanism includes a rotating shaft that passes through the connecting ring. Both ends of the rotating shaft are fixedly connected to upwardly extending fixing rods. The top of the fixing rods are connected to a cross-shaped top frame, and the long end of the cross-shaped top frame is welded with a limit hook.

[0008] As a preferred embodiment of the quick-change support device for idler rollers of this utility model, the limiting hook consists of a horizontal section and an upwardly curved arc section, wherein the horizontal section is fixedly connected to the long end of the cross top frame in parallel.

[0009] As a preferred embodiment of the quick-change support device for idlers of this utility model, the top surface of the cross top frame and the inner arc surface of the limiting hook are provided with anti-slip buffer pads.

[0010] As a preferred embodiment of the quick-change support device for idlers of this utility model, two operating steel pipes are symmetrically hinged to the outer wall of the cylinder of the turnbuckle.

[0011] As a preferred embodiment of the quick-change support device for idler rollers of this utility model, auxiliary support rods distributed in a triangular pattern are welded between the top of the channel steel and the lower screw.

[0012] As a preferred embodiment of the quick-change support device for idler rollers of this utility model, the bottom of the base is fixedly connected with an anti-slip pad.

[0013] The beneficial effects of this utility model are:

[0014] The limit hook is attached to the edge of the belt. The limit hook plays a limiting role to prevent the cross top frame from slipping. The anti-slip buffer pad increases the friction of the contact surface and further prevents the cross top frame from shifting.

[0015] Furthermore, the anti-slip mat (such as rubber with raised texture) contacts the conveyor frame, increasing static friction to prevent the device from sliding laterally under load. At the same time, the base and channel steel form a stable support surface, which can stably support the belt and facilitate the quick replacement of the idlers under the belt by the staff.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-4 The quick-change support device for the idler roller includes a turnbuckle 1, two symmetrically distributed screws 101 connected to the internal thread of the turnbuckle 1, a connecting ring 102 fixed to the top of the top screw 101, and a bottom support mechanism and a top support mechanism respectively provided at the relatively far ends of the two screws 101.

[0024] The bottom support mechanism includes a channel steel 3 fixedly connected to the screw 101 located below. A base 4 is welded and fixed to the bottom of the channel steel 3. The base 4 includes two semi-circular and symmetrically distributed base plates 401. An angle steel 402 is welded and fixed between the two base plates 401.

[0025] The top support mechanism includes a rotating shaft 5 that passes through the connecting ring 102. The two ends of the rotating shaft 5 are fixed with upwardly extending fixing rods 6. The top of the fixing rods 6 are connected to a cross top frame 7. The long end of the cross top frame 7 is welded with a limit hook 701.

[0026] In this embodiment: the cross top frame 7 is placed at the bottom of the belt, and the limiting hook 701 is hooked onto the edge of the belt. Then, the angle steel 402 on the base 4 is clamped onto the corner of the conveyor frame. Next, the two operating steel pipes 2 are rotated to rotate the cylinder of the turnbuckle 1, which can quickly adjust the vertical distance between the top cross top frame 7 and the bottom base 4, so that the cross top frame 7 supports the belt. The limiting hook 701 plays a limiting role to prevent the cross top frame 7 from sliding sideways. The anti-slip pad 403 (such as rubber with raised texture) contacts the conveyor frame, which increases the static friction to prevent the device from sliding laterally under load. The anti-slip buffer pad 702 increases the friction of the contact surface, further preventing the cross top frame 7 from shifting. At the same time, the base 4 and the channel steel 3 form a stable support surface, which can play a role in stabilizing the belt and making it easy for the staff to quickly replace the idler rollers under the belt.

[0027] As a technical optimization of this utility model, the limiting hook 701 is composed of a horizontal section and an upwardly curved arc section, and the horizontal section is fixedly connected to the long end of the cross top frame 7 in parallel.

[0028] In this embodiment: the horizontal section and the long end of the cross top frame 7 are fixed by welding to form a stable horizontal support surface. By placing the cross top frame 7 at the bottom of the belt and hooking the limiting hook 701 on the edge of the belt, the cross top frame 7 plays the role of supporting the belt, and the limiting hook 701 plays the role of limiting and preventing the cross top frame 7 from slipping sideways.

[0029] As a technical optimization of this utility model, the top surface of the cross top frame 7 and the inner arc surface of the limiting hook 701 are provided with anti-slip buffer pads 702.

[0030] In this embodiment: when the cross top bracket 7 is placed against the bottom of the belt, the anti-slip buffer pad 702 is made of rubber, which can absorb impact energy through elastic deformation, increase the friction of the contact surface, and further prevent the cross top bracket 7 from shifting when supporting the belt.

[0031] As a technical optimization of this utility model, the outer wall of the cylinder of the turnbuckle 1 is symmetrically hinged with two operating steel pipes 2.

[0032] In this embodiment: when rotating the cylinder of the turnbuckle 1, the operating steel pipe 2 is rotated (the operating steel pipe 2 can only rotate under the action of external force). The operating steel pipe 2 is radially hinged along the cylinder of the turnbuckle 1, which can be expanded outward or retracted inward, so that it is perpendicular to the axial direction of the cylinder of the turnbuckle 1. This makes it easy to rotate the cylinder of the turnbuckle 1. When not in use, the operating steel pipe 2 can be retracted into the cylinder of the turnbuckle 1 through the hinge shaft, reducing the space occupied by the device when not in use, and facilitating transportation or storage.

[0033] As a technical optimization of this utility model, a triangularly distributed auxiliary support rod 301 is welded between the top of the channel steel 3 and the lower screw 101.

[0034] In this embodiment, the auxiliary support rod 301 forms a rigid triangular frame, which enhances the torsional stiffness of the bottom support mechanism and is especially suitable for stable support under heavy load conditions.

[0035] As a technical optimization of this utility model, the bottom of the base 4 is fixedly connected with an anti-slip pad 403.

[0036] In this embodiment, the anti-slip pad 403 (such as rubber with raised texture) contacts the conveyor frame, and the device is prevented from sliding laterally under load by increasing static friction.

[0037] The working principle and usage process of this utility model are as follows: Place the cross-shaped top bracket 7 at the bottom of the belt and hook the limiting hook 701 onto the edge of the belt. Since the rotating shaft 5 can rotate within the connecting ring 102, the angle of the cross-shaped top bracket 7 can be adjusted via the fixing rod 6 to match belts of various angles, facilitating belt support. Then, the angle steel 402 on the base 4 is secured to the corner of the conveyor frame (the corner of the conveyor frame closest to the belt). Next, rotate the two operating steel pipes 2 to rotate the cylinder of the turnbuckle 1. The symmetrical screws 101 inside will extend and retract synchronously in opposite directions. Adjusting the length of the two screws 101 allows for quick... Adjust the vertical distance between the top cross bracket 7 and the bottom base 4 so that the cross bracket 7 supports the belt. The limit hook 701 acts as a limit to prevent the cross bracket 7 from slipping sideways. The anti-slip pad 403 (such as rubber with raised texture) contacts the conveyor frame to increase static friction and prevent the device from sliding laterally under load. The anti-slip buffer pad 702 increases the friction of the contact surface and further prevents the cross bracket 7 from shifting. At the same time, the base 4 and the channel steel 3 form a stable support surface, and the auxiliary support rod 301 provides auxiliary support, so that the device stably supports the belt and makes it easy for workers to quickly replace the idlers under the belt.
