Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heavy hammer tensioning device, and particularly relates to a heavy hammer tensioning device for limiting rubber belt conveyor. BACKGROUND

[0002] The rubber belt conveyor is used for a long time, and the rubber belt is made of rubber and fiber and has elasticity after being tensioned for a long time. The rubber belt is elongated, and the rubber belt conveyor is prone to slipping or deviation when the load is too large or the friction of the head and tail wheels is not enough, so that the rubber belt conveyor is stopped. Therefore, the rubber belt conveyor must be designed with a tensioning device, and the commonly used tensioning device is a heavy hammer type tensioning device. The existing heavy hammer tensioning device needs to continuously use its own tension to pull and tighten the rubber belt when the rubber belt is tensioned. In this case, the rubber belt is always in a high tension state, so that the rubber belt is easily broken due to slight wear during use, thereby shortening the service life of the rubber belt and increasing the use cost of the conveyor.

[0003] Therefore, based on this, a design or technical improvement is proposed to solve the above problems.

[0004] The above content is only used to assist in understanding the technical solutions of the present application, and does not mean that the above content is the closest prior art. SUMMARY

[0032] In an embodiment, the tensioning mechanism includes a tensioning roller 2 that is sleeved with the conveying belt 13, a weight box 21 that is arranged at the lower end of the tensioning roller 2 and is limited to slide on the sliding guide 11, and a bearing frame 22 that is arranged on the weight box 21 and is rotationally connected with the tensioning roller 2, the tensioning roller 2 is sleeved with the reversing section of the conveying belt 13, then the tensioning roller 2 and the weight box 21 are connected through the bearing frame 22, so that the weight of the weight box 21 is used to pull the conveying belt 13 downward, so that the conveying belt 13 is taut, and the internal tension of the conveying belt 13 is maintained.

[0033] In an embodiment, the tensioning control mechanism includes a supporting assembly arranged on the sliding guide 11 for providing additional support to the conveying belt 13, and a limiting assembly arranged on the supporting assembly for limiting the weight box 21, the additional support of the supporting assembly enables the tension between the conveying belt 13 and the supporting assembly to interact, and different activities are generated according to the different internal tensions of the conveying belt 13, and then the limiting assembly is controlled by the supporting assembly, so that when the internal tension of the conveying belt 13 changes, the limiting state of the weight box 21 can be changed, and then the tension of the conveying belt 13 is adjusted by the weight box 21 to keep stable.

[0034] In an embodiment, the supporting assembly includes a pressure regulating assembly arranged on the sliding guide 11 and a pressure bearing assembly arranged on the pressure regulating assembly for supporting the conveying belt 13, the pressure regulating assembly is used to adjust the supporting degree of the pressure bearing assembly to the conveying belt 13, and the pressure regulating assembly is arranged to pre-adjust the internal tension of the conveying belt 13, and then the tension is detected by the abutment between the pressure bearing assembly and the conveying belt 13, and then when the internal tension of the conveying belt 13 changes, the pressure bearing assembly makes corresponding movement to control the limiting assembly to work.

[0035] In an embodiment, the pressure regulating assembly comprises a track block 3 arranged at the end of the sliding guide frame 11 away from the base 1 and having a track slot 31 at the upper end, a abutting frame movably arranged in the track slot 31 for supporting the pressure bearing assembly, and a regulating assembly arranged at the side of the track block 3 away from the abutting frame for adjusting the supporting force of the abutting frame. The abutting frame comprises a threaded sleeve block 32 limitedly sliding in the track slot 31, a top supporting arm 33 movably penetrating the track block 3 and limitedly sliding in the track slot 31, and a pre-adjusting spring 34 arranged in the track slot 31 and having one end arranged on the threaded sleeve block 32 and the other end arranged on the top supporting arm 33. By sliding the threaded sleeve block 32 in the track slot 31, the pre-adjusting spring 34 is compressed to provide greater elastic support to the top supporting arm 33.

[0036] In an embodiment, the regulating assembly comprises a bidirectional threaded screw rod 35 threadedly connected with the threaded sleeve block 32, and a drive control electric box 36 arranged at the side of the track block 3 away from the top supporting arm 33 and connected with the bidirectional threaded screw rod 35. The elastic force of the pre-adjusting spring 34 is changed by driving the bidirectional threaded screw rod 35 to work by the drive control electric box 36, so that the threaded sleeve blocks 32 at both ends of the bidirectional threaded screw rod 35 move in opposite directions, so that the pre-adjusting springs 34 at both ends are synchronously contracted and elongated, and the top supporting arms 33 at both sides work under the same supporting force.

[0037] In an embodiment, the pressure bearing assembly comprises a limiting frame 4 arranged at both sides of the track block 3, a side movable frame 41 limitedly sliding on the limiting frame 4, and a tension roller 42 bearing connected with the side movable frame 41 and arranged between the redirecting roller 14 and the tensioning roller 2 and abuttingly engaged with the conveying belt 13. A abutting head 43 is further arranged on the side movable frame 41 and slidably abutting with the top supporting arm 33. The side movable frame 41 can slide transversely on the limiting frame 4 to synchronously move the tension roller 42. Then, by adjusting the tension roller 42 and the conveying belt 13, the conveying belt 13 applies an inward abutting force to the tension roller 42 under the full tension, so that the abutting head 43 abuttingly contacts with the top supporting arm 33. When the tension roller 42 is stable, the elastic force of the pre-adjusting spring 34 and the tension of the conveying belt 13 are kept at a fixed corresponding value, so that the tension of the conveying belt 13 is pre-adjusted by changing the elastic force of the pre-adjusting spring 34.

[0038] In an embodiment, the weight box 21 is further provided with a plurality of sets of bolt slot 5, and the limiting assembly comprises a side connecting wall plate 51 provided on the side movable frame 41 and a bolt rod 52 provided on the side connecting wall plate 51 and matched with the bolt slot 5. The bolt rod 52 is locked with the bolt slot 5 to keep the weight box 21 stable, so that the weight box 21 does not continuously exert the pulling force of its own gravity on the conveying belt 13. When the tension inside the conveying belt 13 is insufficient, the side connecting wall plate 51 will move to the side end, so that the bolt rod 52 is separated from the bolt slot 5, and the weight box 21 is moved downward to provide greater pulling force for the conveying belt 13, so that the tension inside the conveying belt 13 is increased.

[0039] In an embodiment, the sliding guide frame 11 is further provided with a safety blocking frame 6, and the safety blocking frame 6 is further provided with a buffer spring 61 connected at one end with the safety blocking frame 6 and at the other end with the weight box 21. Through the provision of the buffer spring 61, the lower end of the weight box 21 is provided with a certain supporting force. The buffer spring 61 is initially in a free state, and the maximum elastic force inside the buffer spring 61 is less than the gravity of the weight box 21, so that the weight box 21 can continuously move downward, and the buffer spring 61 provides buffering for the weight box 21 during the continuous downward movement of the weight box 21, so as to avoid the weight box 21 from rapidly falling and generating high impact force on the conveying belt 13 to cause the conveying belt 13 to break.

[0040] The specific working mode of the device is: before the transmission machine works, the tension roller 2 is sleeved with the conveying belt 13, and then the tension roller 42 is sleeved with the conveying belt 13, the two-way screw rod 35 is driven to rotate through the control electric box 36, then the threaded sleeve block 32 on both sides is relatively moved, the pre-adjusting spring 34 is contracted, so that the top supporting arm 33 provides greater elastic force, the top supporting arm 33 provides greater abutting force to the abutting head 43 under the action of the elastic force, the tension roller 42 generates higher abutting force to the conveying belt 13, and the pin rod 52 is always in the pinning state with the pin slot 5 under the abutting force, then the transmission machine is started, so that the conveying belt 13 starts to drive, when the conveying belt 13 is used for a period of time and the internal tension is reduced, the abutting force of the conveying belt 13 to the tension roller 42 is insufficient, then the tension roller 42 moves to the side of the conveying belt 13 under the abutting action of the top supporting arm 33, so as to drive the side movable frame 41 to move synchronously, then the pin rod 52 is pulled out from the inside of the pin slot 5 through the side connecting wall plate 51, so that the weight box 21 pulls the tension roller 2 to move downward through the bearing frame 22, so that the pulling force received by the conveying belt 13 increases, so as to increase the tension of the conveying belt 13, the increase of the internal tension of the conveying belt 13 increases the abutting force of the conveying belt 13 to the tension roller 42, so as to make the side movable frame 41 return, so that the pin rod 52 is inserted and pinned with another set of pin slots 5 on the weight box 21, so as to lock the weight box 21, so that the conveying belt 13 always maintains the best tension state to run, and when the conveying belt 13 is used to the limit of rupture, the weight box 21 is buffered through the buffer spring 61, so as to avoid the impact caused by the rapid falling to cause the damage of the components.

[0041] It is apparent for those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalents of the claims are intended to be embraced therein.
