Description

TECHNICAL FIELD

[0001] The utility model belongs to the auxiliary frock field, concretely relates to a kind of auxiliary support mechanism for replacing carrier roller. BACKGROUND

[0002] In coal preparation plant, chemical plant and so on workshop plant building transport material, need a large number of belt conveyor, belt conveyor needs a large number of carrier roller to support belt and carry out material transmission, so carrier roller is also in the state of continuous operation, and belt carrier roller is often damaged due to bearing wear and other reasons, and maintenance frequency is faster.Therefore, in the maintenance of belt conveyor, the carrier roller with abnormal sound and non-rotation needs to be replaced in time.The existing carrier roller needs to be replaced, and multiple people need to cooperate, the belt above the carrier roller is first pried up using a crowbar, and then the carrier roller below the belt is removed and replaced.In this process, the belt needs to be kept pried up all the time, which makes the labor intensity of manual work large and does not have sustainability, thus making the maintenance efficiency low, and a high degree of cooperation is required, which has safety hazards. SUMMARY

[0003] The utility model discloses a kind of auxiliary support mechanisms for replacing carrier roller, which can reduce the number of manual work and labor intensity, greatly improve maintenance efficiency.

[0004] The utility model discloses a kind of auxiliary support mechanisms for replacing carrier roller, which can reduce the number of manual work and labor intensity, greatly improve maintenance efficiency.

[0005] An auxiliary support mechanism for replacing carrier roller includes a base, a hydraulic cylinder, a support rod and a hook angle, the base is plate-shaped, the hydraulic cylinder is vertically installed on the surface of the base, a transmission fork is threadedly connected to the top of the hydraulic cylinder, the hydraulic cylinder is detachably connected to the top of the transmission fork by bolts, and the hook angle is hinged to the side of the base.

[0006] The hook angle is an acute angle, and the opening direction of the hook angle faces downward.

[0007] The support rod can be made of a steel pipe or an angle steel, and the support rod can also be replaced by a steel plate.

[0008] The auxiliary support mechanism for replacing carrier roller has the following beneficial effects:

[0009] (1) By installing a support rod on the hydraulic cylinder, the process of manually lifting the belt with a crowbar can be replaced, and the support process is more stable.

[0010] (2) By setting an acute hook angle, the opening of the hook angle faces downward, which can stably and conveniently install the base on the surface of the carrier roller frame. BRIEF DESCRIPTION OF DRAWINGS

[0011] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0015] like Figure 1 , Figure 2 As shown, the auxiliary support mechanism for replacing idler rollers provided in this embodiment includes a base 1, a hydraulic cylinder 2, a support rod 3, and a hook 4. The base 1 is plate-shaped, and the hydraulic cylinder 2 is vertically mounted on the surface of the base 1. A transmission fork 5 is threadedly connected to the top of the hydraulic cylinder 2. The transmission fork 5 includes an integrally formed nut and connecting ears symmetrically connected to the nut along the central axis. A horizontally arranged through hole is machined on the upper part of the connecting ears. The hydraulic cylinder 2 is detachably connected to the top of the transmission fork 5 by bolts. The support rod 3 can be made of steel pipe or angle steel. The hook 4 is hinged to the side of the base 1. The hook 4 is an acute angle, and the opening direction of the hook 4 faces downwards from the base 1. The support rod 3 forms a force-saving lever along the bolts.

[0016] To broaden the applicability of the support mechanism, the support rod 3 can be replaced with a steel plate, with protrusions machined at the joints of the steel plate to connect with the transmission fork 5.

[0017] To further improve the stability of the base 1, the base 1 is provided with an upwardly curved bending part 6 on the side near the hook corner 4. Multiple ribs 7 are also provided between the bending part 6 and the flat part where the hydraulic cylinder 2 is installed. By using the bending part 6 and the hinged hook corner, it can adapt to the fixation of various complex planes.

[0018] The method of using this utility model is as follows:

[0019] In use, the hooking corner 4 is first extended into the support frame under the to-be-replaced carrier roller, then the hooking corner 4 is used to hook the support frame to improve the stability of the base 1, then the hydraulic cylinder 2 is controlled to be elongated, the transmission fork 5 is close to the ground, then the support rod 3 is rotated, the belt can be lifted up by the lever principle, and then space is left for the replacement of the carrier roller.

[0020] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any modification and replacement based on the technical solutions and inventive concepts provided by the present application should be covered within the protection scope of the present application.
