Description

Belt supporting trolley for long-distance belt conveyor track

Technical Field

The utility model belongs to the technical field of belt conveyors, and particularly relates to a carrier belt trolley for a long-distance belt conveyor track.

Background

The long-distance belt conveyor is large in tensioning stroke, when the belt conveyor is tensioned in a vehicle tensioning mode, after the tensioning vehicle is tensioned on the track, a section of conveying belt which is several meters long is provided with no supporting roller, the conveying belt sags, so that the conveying belt is commonly called drooping, the conveying belt is not beneficial to transporting materials, friction is increased, belt speed is influenced, and the service life of the conveying belt is shortened. The carrier band dolly can be on the track operation and support the conveyer belt, has following problem in the use: (1) The travelling range of the carrier band trolley is not limited, and the distance between supporting carrier rollers between the conveying belts cannot be ensured; (2) The supporting belt trolley and the tensioning device are easy to collide and damage, the service life of the equipment is short, and the maintenance cost is high.

Disclosure of Invention

The technical problem to be solved by the utility model is to provide the carrier belt trolley for the long-distance belt conveyor track, which can ensure the distance between the carrier rollers of the conveyor belt and avoid damage caused by collision with the tensioning device.

In order to achieve the above purpose, the technical scheme of the utility model is as follows: the carrier belt trolley for the long-distance belt conveyor track comprises a frame, wheels capable of walking along the track are fixedly arranged at the bottom of the frame, carrier belt carrier rollers are arranged at the top of the frame, and limiting ring chains are respectively connected to two sides of the frame along the walking direction; the side part of the frame is provided with a buffer mechanism.

As the preferable technical scheme, the wheels are fixed on the bending plate through the shaft and the clamping plate, and the wheels, the shaft, the clamping plate and the bending plate form a set of wheel sets.

As an optimal technical scheme, the wheel set is detachably connected with the frame through bolts.

As the preferable technical scheme, the two sides of the top of the frame are respectively fixedly provided with a bearing seat, and two ends of the carrier roller are respectively arranged on the bearing seats through outer spherical ball bearings.

As an optimal technical scheme, the frame is of a trapezoid structure with a small upper end and a large lower end.

As an optimal technical scheme, the buffer mechanism comprises a buffer arm, and a polyurethane buffer block is fixedly arranged at the outer end of the buffer arm.

Due to the adoption of the technical scheme, the utility model has at least the following beneficial effects:

(1) The carrier roller is installed at the top of frame, the both sides of frame are connected with spacing ring chain respectively along the direction of travel, have restricted the dolly walking scope through spacing ring chain, utilize the carrier roller at dolly and dolly top of limited walking scope, have guaranteed the interval of conveyer belt support bearing roller, have avoided the conveyer belt sagging in the tensioning scope.

(2) The wheels are fixed on the bending plate through the shafts and the clamping plates, the wheels, the shafts, the clamping plates and the bending plate form a set of wheel sets, the wheel sets are detachably connected with the frame through bolts, and the carrier band trolley is convenient to detach.

(3) The lateral part of frame is provided with buffer gear, and buffer gear can avoid riding belt dolly and straining device collision to appear damaging, and buffer gear adopts polyurethane buffer block, and polyurethane buffer block not only can absorb a large amount of impact properties, still has higher impact elasticity, good resistance to compression resilience can prolong equipment life, reduces maintenance cost.

(4) The two ends of the carrier roller are respectively arranged on the bearing seat through the outer spherical ball bearings, the outer spherical ball bearings can bear large force, the carrier roller adopting the outer spherical ball bearings has stronger bearing capacity and larger application range.

The following drawings are only for purposes of illustration and explanation of the present utility model and are not intended to limit the scope of the utility model. Wherein:

FIG. 1 is a schematic diagram of a front view of an embodiment of the present utility model;

FIG. 2 is a schematic side view of an embodiment of the present utility model;

fig. 3 is a partial enlarged view at I in fig. 2.

Detailed Description

The utility model is further illustrated in the following, in conjunction with the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present utility model are described by way of illustration only. It is needless to say that the person skilled in the art realizes that the described embodiments may be modified in various different ways without departing from the spirit and scope of the utility model. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive in scope.

As shown in fig. 1 and 2, the carrier band trolley for the long-distance belt conveyor track comprises a frame 1, wheels 3 capable of walking along a track 2 are fixedly arranged at the bottom of the frame 1, carrier band carrier rollers 4 are arranged at the top of the frame 1, limiting ring chains 5 are respectively connected to two sides of the frame 1 along the walking direction, the trolley walking range is limited by the limiting ring chains 5 fixed to two sides, the spacing between the carrier band supporting carrier rollers and the carrier band carrier rollers is ensured by utilizing the trolley with the limited walking range and the carrier band carrier rollers 4 at the top of the trolley, and the sagging of the carrier band in the tensioning range is avoided.

Referring to fig. 1 and 3, in this embodiment, the wheel 3 is fixed to the bending plate 33 by the axle 31 and the clamping plate 32, and the wheel 3, the axle 31, the clamping plate 32 and the bending plate 33 form a set of wheel sets.
