Description

Technical Field

[0001] The utility model relates to a mechanical device for traction and release of a conveyor belt, in particular to a special traction and release device for a long-distance spectacles roll conveyor belt. Background Art

[0002] Currently, traditional 250-meter single-roll conveyor belts are only suitable for replacing short-distance conveyor belts. However, the conveyor belts used at docks are usually long-distance conveyor belts exceeding 1,500 meters in length. If these long-distance conveyor belts are replaced, not only will multiple 250-meter single-roll conveyor belts be required, but these single-roll conveyor belts will also need to be connected one by one through multiple vulcanized joints after being released. This leads to a large number of vulcanized joints, consumes a lot of manpower, and also requires the relevant production process to be shut down, which also has a certain impact on production. Of course, if a longer conveyor belt is used, the above technical problems can be effectively solved. According to actual use, a conveyor belt length of 500 meters is the most efficient. However, considering the limitations of transportation conditions, the height of a 500-meter single roll often exceeds 2.9 meters. Therefore, 500-meter conveyor belts are usually transported in the form of eyeglass rolls, that is, the 500-meter conveyor belt is wound into an exposed roll and a one-way roll. In this way, the exposed roll and the one-way roll can ensure that the entire 500-meter conveyor belt is wound and stored without causing the single roll to be wound too high. However, due to the winding form of the outcrop roll, when the traction head on the outcrop roll is pulled outwards and drives the outcrop roll to passively rotate and release the conveyor belt, there are usually Figure 11 As shown in the situation where 1 meter needs to be pulled out and 1 meter of excess needs to be pulled out at the same time, after the conveyor belt on the exposed roll is released, it will eventually result in nearly 120 meters of excess conveyor belt having nowhere to go. In this way, the long-distance conveyor belt wound and stored in the form of eyeglass rolls cannot solve the problem of pulling out 1 belt 1, and cannot be pulled and released quickly and efficiently.

[0029] Special traction release device for long-distance glasses roll conveyor belt, such as Figures 1 to 5 As shown, it is mainly used for traction and release of the spectacles roll conveyor belt, and its structure includes a base frame 1, an exposed head bracket 3 and a one-way bracket 2 on the base frame, and a conveyor belt wound into a spectacles roll 4. The spectacles roll 4 is composed of an exposed head roll 42 and a one-way roll 41 wound by the conveyor belt, and a traction head 422 of the conveyor belt is reserved on the exposed head roll 42.

[0030] Described chassis 1 is a Figure 6 The quadrilateral frame shown in FIG. 1 has a pair of exposed brackets 3 and one-way brackets 2, and the pair of exposed brackets 3 are symmetrically mounted on both sides of the base frame 1, and the pair of one-way brackets 2 are also symmetrically mounted on both sides of the base frame 1. Figure 3 As shown, a pair of exposed brackets 3 are arranged at the left end of the chassis 1. Figure 3 It is shown arranged at the right end of the chassis 1.

[0031] Each of the one-way brackets 2 is a trapezoidal frame composed of a top cross bar 21 and side bars 22 supported at both ends of the top cross bar. A vertical slot 23 is provided on the top cross bar, specifically, the vertical slot is designed to be a U-shaped slot with an open top. A reinforcing vertical bar 24 is provided between the top cross bar 21 and the base frame 1, and a support 62 is provided on the reinforcing vertical bar for the installation of the reducer 6; at the same time, a horizontally installed drive shaft 61 is provided between the reinforcing vertical bars 24 of a pair of one-way brackets 2, specifically, the two ends of the drive shaft are respectively supported by bearings between the reinforcing vertical bars 24 of a pair of one-way brackets 2, and are driven by the reducer 6 to form forward and reverse rotation.

[0032] Each of the exposed brackets 3 is a triangular frame composed of a central vertical rod 31 and oblique rods 32 respectively supported on the top of the central vertical rod. A pair of rotating wheels 33 is provided on the top of the central vertical rod 31.

[0033] The exposed roll 42 is rotatably placed on the exposed bracket 3. Specifically, the two ends of the exposed roll core 421 of the exposed roll 42 are tangentially supported between a pair of rotating wheels 33, so that the exposed roll 42 rotates around the exposed roll core 421 between the pair of exposed brackets 3.

[0034] The one-way roll 41 is rotatably placed on the one-way bracket 2. Specifically, the ends of the one-way roll core 411 of the one-way roll 41 are rotatably supported in the vertical slots 23, thereby allowing the one-way roll 41 to rotate around the one-way roll core 411 between the pair of one-way brackets 2. Furthermore, the exposed roll core 421 and the one-way roll core 411 are both placed horizontally and parallel to each other.

[0035] The drive shaft 61 is located below the installed one-way roll 41, and the drive shaft 61 directly contacts the outer roll surface of the one-way roll 41, thereby driving the one-way roll 41 to rotate forward and backward.

[0036] At the same time, as the drive shaft 61 drives the one-way roll 41 to rotate forward and backward, that is, the forward and reverse rotation of the one-way roll will wind the conveyor belt inward or release the conveyor belt outward, when the one-way roll 41 winds the conveyor belt inward, that is, the one-way roll 41 rotates forward to wind the conveyor belt and increase the roll diameter, the increased roll diameter will force the one-way roll core 411 to move upward along the vertical groove 23. When the one-way roll 41 releases the conveyor belt outward, that is, the one-way roll 41 rotates backward to release the conveyor belt and reduce the roll diameter, the reduced roll diameter will cause the one-way roll core 411 to move downward along the vertical groove 23 under the action of gravity. The purpose of such a structure is to allow the outer roll surface of the one-way roll 41 to always contact the drive shaft 61 and be driven.

[0037] The one-way bracket 2 is provided with a guide wheel 5 that is attached to the outer side of the one-way roll 41, and the guide wheel assists the one-way roll in winding the conveyor belt or releasing the conveyor belt. This embodiment designs a pair of one-way brackets 2, so each one-way bracket is provided with a guide wheel 5, which is respectively attached to the two outer sides of the one-way roll 41, thereby preventing the conveyor belt from winding off.

[0038] One end of the guide wheel 5 on each side is rotatably mounted on the one-way bracket 2 through a hinge hole 53. Therefore, the guide wheel 5 only needs to rotate relative to the one-way bracket 2 around the hinge hole 53 at this end to rotate upward to disengage from the outer side of the one-way roll 41 or rotate downward to fit into the outer side of the one-way roll 41.

[0039] Among them, the one-way bracket 2 is also provided with a number of limiting holes 52, which are arranged in sequence along the rotation arc of one end of the guide wheel 5, and a locking hole 51 is correspondingly provided at one end of the guide wheel 5. The locking hole can selectively lock the number of limiting holes 52 as the guide wheel 5 rotates relative to the one-way bracket 2, thereby forming multiple rotation angles of the guide wheel 5. For example, after the locking hole 51 overlaps with one of the limiting holes 52 as the guide wheel 5 rotates, it is only necessary to insert the locking pin into the overlapping locking hole 51 and the limiting hole 52 to limit the continued rotation of the guide wheel 5, thereby locking the use angle of the guide wheel 5. This structure mainly allows the guide wheel 5 to adjust the fitting position with the outer side surface according to the roll diameter of the one-way roll 41.

[0040] The working process of the utility model is as follows Figures 7 to 10 As shown: when the traction head 422 on the exposed roll 42 is pulled outward and drives the exposed roll to passively rotate and release the conveyor belt, the drive shaft 61 will cooperate with the driven one-way roll 41 to rotate synchronously and wind the conveyor belt, that is, when the exposed roll 42 is pulled out 1 meter, the 1 meter surplus that needs to be pulled out will be synchronously rotated forward and wound by the one-way roll 41 until the conveyor belt on the exposed roll is released. At this time, the traction head 422 is continued to be pulled outward to drive the one-way roll 41 to reverse, and then drive the reversed one-way roll to rotate and release the conveyor belt, thereby solving the problem of pulling out the exposed belt 42, so the conveyor belt can be pulled and released quickly and efficiently, ensuring that the belt conveyor on the dock can more conveniently replace long-distance conveyor belts.

[0041] In addition, since the weight of the one-way roll 41 of the synchronously wound conveyor belt will gradually increase with the increase of the roll diameter, it is necessary to drive the one-way roll 41 to reverse through the drive shaft 61, so as to assist the traction head 422 to pull the one-way roll 41 outward to reverse and release the conveyor belt, until the one-way roll reduces the roll diameter as it reverses and releases the conveyor belt, it can drive the one-way roll core 411 of the one-way roll to move downward and contact the bottom of the vertical groove 23. At this time, the overall weight of the one-way roll 41 has also been greatly reduced, so the drive shaft 61 can stop driving, and the traction head 422 can continue to pull the one-way roll 41 outward to passively reverse and continue to release the conveyor belt.

[0042] The above embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should also be understood that after reading the contents of the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope of the claims appended hereto.
