Description

Technical Field

[0001] The utility model relates to the technical field of telescopic belt conveyors, and more specifically, to a telescopic belt conveyor. Background Art

[0002] A telescopic belt conveyor (also known as a telescopic loading machine) can freely expand and contract in the length direction, and can control the length of the conveyor at any time. It can convey materials in both directions and can be used in conjunction with other conveying equipment and material sorting systems to realize the automated production of material storage and retrieval or vehicle loading and unloading, and is widely used in various industries. The telescopic belt conveyor is mainly divided into a main body and a telescopic section.

[0003] When the existing telescopic belt conveyor is in use, it is usually supported and stabilized by the main body. Moreover, after the telescopic section is fully extended, the extended part of the telescopic section is in a suspended state. If the mass of the transported object is relatively large, when the object is conveyed to the end of the suspended section, it is very easy to cause the end of the suspended section to be overweight and the device to tip over. Therefore, the stability of the device needs to be improved. In view of this, we propose a telescopic belt conveyor. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a telescopic belt conveyor to solve the technical problem of poor stability of the current telescopic belt conveyor.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A telescopic belt conveyor includes a telescopic belt conveyor main body. A first telescopic section is arranged above the telescopic belt conveyor main body. A second telescopic section is arranged on the first telescopic section. Two groups of symmetric support legs and elastic rods are hinged and arranged at the front end of the bottom of the second telescopic section. The support legs are located between the elastic rods and the first telescopic section. A notch is formed on one side of the support leg facing the elastic rod, and the bottom end of the elastic rod is located in the notch. A through hole is formed at the bottom of the notch;

[0006] A top block is slidably arranged inside the through hole. An installation plate is arranged at the front end of the first telescopic section. A groove is formed at the top of the installation plate. The front side of the installation plate is an inclined surface. Rollers are rotatably arranged at the bottom and top of the inclined surface. Round head end blocks are arranged at both ends of the bottom of the inclined surface, and the round head end blocks are symmetrically arranged with the top block.

[0007] The utility model arranges a support leg and an elastic rod on the second telescopic section of the telescopic belt conveyor body. Therefore, when the second telescopic section is extended from the first telescopic section, the support leg will rotate to a vertical state, and the bottom end of the elastic rod will press against the bottom of the notch on the support leg, thereby vertically fixing the support leg, so that the suspended end of the telescopic belt conveyor body can be supported and fixed, which can greatly improve the overall stability of the device. Even if some objects with larger mass are transported, the device will not overturn. Therefore, when the elastic rod vertically fixes the support leg, the bottom end of the elastic rod will push into the through hole, and the bottom end part of the elastic rod will extend into the inside of the through hole, thereby forming a limited top fixation, which can greatly ensure the stability of the vertical top fixation of the support leg by the elastic rod, thereby ensuring the stability of the support leg supporting the suspended end of the telescopic belt conveyor body. Qualitatively, in the process of the second telescopic section contracting to the first telescopic section, the round head end block on the inclined surface will contact the top block and push the top block forward a short distance. At this time, the top block will push the bottom end of the elastic rod outward to make it disengage from the through hole, and then the roller at the bottom of the inclined surface will contact the leg in advance to limit the leg, causing the leg to rotate and the elastic rod to retract. When the leg rotates to a certain extent, the roller at the top of the inclined surface limits the leg, allowing the leg to continue to rotate until the second telescopic section is contracted. At this time, the leg is horizontally attached to the bottom of the second telescopic section, thereby realizing the automatic storage effect of the leg and improving the convenience of leg storage. Moreover, under the limited cooperation of the roller, when the second telescopic section is extended, the leg will slowly rotate downward, so that the elastic rod can stably extend to support the leg, which can avoid the situation where the end of the elastic rod is separated from the leg.

[0008] Preferably, a screw is screwed onto the bottom of the leg, and a support block is arranged at the bottom of the screw.

[0009] Preferably, a concave frame is arranged on the top of the supporting leg, the concave frame is connected to the second telescopic section, connecting ends are rotatably arranged on both sides of the inside of the concave frame, and the connecting ends are connected to the supporting leg.

[0010] Preferably, the elastic rod comprises a tube body, a rod body is inserted into the bottom end of the tube body, a spring is arranged inside the tube body, the bottom end of the rod body is located in a slot, an open slot is provided at the top end of the tube body, a mounting shaft is rotatably arranged inside the open slot, a connecting block is arranged on the mounting shaft, and the connecting block is connected to the second telescopic section.

[0011] Preferably, slide grooves are provided on both sides of the top block, and sliding blocks are slidably arranged inside the slide grooves, and the sliding blocks are connected to the inner wall of the through hole.

[0012] Preferably, the rear side of the notch is inclined, and the front end of the top block is inclined.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, legs and elastic rods are provided on the second telescopic section of the telescopic belt conveyor main body. Therefore, when the second telescopic section extends from the first telescopic section, the legs will rotate to a vertical state, and the bottom end of the elastic rod will abut against the bottom of the notch on the legs, thereby vertically fixing the legs, so that the suspended end of the telescopic belt conveyor main body can be supported and fixed, greatly improving the overall stability of the device. Even when transporting some heavy objects, the device will not tip over, solving the technical problem of poor stability of the current telescopic belt conveyor. Therefore, the present utility model has the advantage of good stability.

[0015] 2. The present utility model also has through holes provided at the bottom of the notch. Therefore, when the elastic rod vertically presses and fixes the legs, the bottom end of the elastic rod will be inserted into the through holes, and a part of the bottom end of the elastic rod will extend into the interior of the through holes, thereby forming a limiting pressing and fixing, which can greatly ensure the stability of the elastic rod vertically pressing and fixing the legs, and thus ensure the stability of the legs supporting the suspended end of the telescopic belt conveyor main body.

[0016] 3. The present utility model also has a mounting plate provided on the first telescopic section, a top block arranged inside the through hole, and the front side of the mounting plate is an inclined surface, on which a roller and a round head end block are arranged. Therefore, during the process of the second telescopic section retracting into the first telescopic section, the round head end block on the inclined surface will contact the top block and push the top block forward a short distance. At this time, the top block will push the bottom end of the elastic rod outward, causing it to disengage from the through hole. Then, the roller at the bottom of the inclined surface will contact the legs in advance to limit the legs, causing the legs to rotate and the elastic rod to retract. When the legs rotate to a certain extent, the roller at the top of the inclined surface limits the legs, causing the legs to continue to rotate until the second telescopic section retracts completely. At this time, the legs are horizontally attached to the bottom of the second telescopic section, thus achieving the automatic storage effect of the legs, improving the convenience of leg storage. And with the limiting cooperation of the rollers, when the second telescopic section extends, the legs will slowly rotate downward, so that the elastic rod can stably extend to support the legs, and the situation where the end of the elastic rod disengages from the legs can be avoided.

[0026] Such as Figures 1 to 7As shown in the figure, the utility model relates to a telescopic belt conveyor, which includes a telescopic belt conveyor main body 1. A first telescopic section 101 is arranged above the telescopic belt conveyor main body 1, and a second telescopic section 102 is arranged on the first telescopic section 101. Two groups of symmetric legs 2 and elastic rods 3 are hinged at the front end of the bottom of the second telescopic section 102. The legs 2 are located between the elastic rods 3 and the first telescopic section 101. A notch 201 is formed on one side of the leg 2 facing the elastic rod 3, and the bottom end of the elastic rod 3 is located in the notch 201. A through hole 202 is formed at the bottom of the notch 201. When the telescopic belt conveyor main body 1 is in use, the telescopic conveying effect is achieved through the extension of the first telescopic section 101 and the second telescopic section 102. This is the prior art and will not be elaborated here. When the second telescopic section 102 extends from the first telescopic section 101, the legs 2 will rotate to a vertical state, and the bottom end of the elastic rod 3 will abut against the bottom of the notch 201 on the leg 2, thereby vertically fixing the leg 2. Thus, the suspended end of the telescopic belt conveyor main body 1 can be automatically supported and fixed, which can greatly improve the overall stability of the device. Even when conveying some heavy objects, the device will not tip over. Moreover, when the elastic rod 3 vertically fixes the leg 2, the bottom end of the elastic rod 3 will be inserted into the through hole 202 at the bottom of the notch 201, and a part of the bottom end of the elastic rod 3 will extend into the interior of the through hole 202, thereby forming a limit fixing, which can greatly ensure the stability of the elastic rod 3 vertically fixing the leg 2, and thus ensure the stability of the leg 2 supporting the suspended end of the telescopic belt conveyor main body 1.

[0027] Specifically, a screw 208 is screwed at the bottom of the leg 2, and a support block 209 is arranged at the bottom of the screw 208. Before use, the screw 208 can be turned according to the height of the suspended end plane to adjust the height of the leg 2, so as to facilitate the leg 2 to support on the plane for force when it is vertical.

[0028] Furthermore, a concave frame 206 is arranged at the top of the leg 2. The concave frame 206 is connected to the second telescopic section 102. Connecting ends 207 are rotatably arranged on both sides inside the concave frame 206, and the connecting ends 207 are connected to the leg 2. With the cooperation of the concave frame 206 and the connecting ends 207, the leg 2 can rotate by 90°. And when the leg 2 is vertical, one side of the concave frame 206 limits it to prevent it from continuing to rotate to one side.

[0029] Furthermore, the elastic rod 3 includes a tube body 301, a rod body 302 is inserted into the bottom end of the tube body 301, a spring 303 is arranged inside the tube body 301, the bottom end of the rod body 302 is located in the slot 201, an open slot 304 is opened at the top of the tube body 301, a mounting shaft 305 is rotatably arranged inside the open slot 304, a connecting block 306 is arranged on the mounting shaft 305, and the connecting block 306 is connected to the second telescopic section 102. With the cooperation of the open slot 304, the mounting shaft 305 and the connecting block 306, the elastic rod 3 can rotate to a certain extent. With the cooperation of the spring 303, as the leg 2 rotates downward, the spring 303 will push the rod body 302 out of the tube body 301 until the leg 2 is vertical. At this time, the bottom end of the rod body 302 is against the bottom of the slot 201 of the leg 2, thereby fixing the leg 2.

[0030] In the embodiment of the utility model, a top block 203 is slidably arranged inside the through hole 202, a mounting plate 4 is arranged at the front end of the first telescopic section 101, a groove 401 is opened on the top of the mounting plate 4, the front side of the mounting plate 4 is an inclined surface, and rollers 402 are rotatably arranged at the bottom and top of the inclined surface, round-headed end blocks 403 are arranged at both ends of the bottom of the inclined surface, and the round-headed end blocks 403 are symmetrically arranged with the top block 203. During the process of the second telescopic section 102 contracting to the first telescopic section 101, the round-headed end blocks 403 on the inclined surface of the mounting plate 4 will contact with the top block 203 and push the top block 203 forward a short distance. At this time, the top block 203 pushes the bottom end of the elastic rod 3 outward to make it disengage from the through hole 202, and then the bottom of the inclined surface of the mounting plate 4 The roller 402 will contact the leg 2 in advance to limit the leg 2, causing the leg 2 to rotate and the elastic rod 3 to retract. When the leg 2 rotates to a certain extent, the roller 402 on the top of the inclined surface of the mounting plate 4 limits the leg 2, causing the leg 2 to continue to rotate until the second telescopic section 102 is completely contracted. At this time, the leg 2 is horizontally attached to the bottom of the second telescopic section 102, thereby achieving an automatic storage effect on the leg 2 and improving the convenience of storing the leg 2. Moreover, under the limited cooperation of the roller 402, when the second telescopic section 102 is extended, the leg 2 will slowly rotate downward, thereby allowing the elastic rod 3 to stably extend to support the leg 2, thereby preventing the end of the elastic rod 3 from detaching from the leg 2.

[0031] Specifically, slide grooves 204 are provided on both sides of the top block 203, and sliders 205 are slidably arranged inside the slide grooves 204. The sliders 205 are connected to the inner wall of the through hole 202. With the cooperation of the slide grooves 204 and the sliders 205, the top block 203 can be slidably installed.

[0032] Furthermore, the rear side of the slot 201 is inclined, and the front end of the top block 203 is inclined. The inclined surface of the rear side of the slot 201 facilitates the retraction and upward movement of the bottom end of the elastic rod 3. The inclined surface of the front end of the top block 203 facilitates the process of pushing the bottom end of the elastic rod 3 out of the through hole 202, so that its bottom end moves upward and contacts the inclined surface of the rear side of the slot 201.

[0033] Working principle: This embodiment provides a telescopic belt conveyor. First, when the telescopic belt conveyor body 1 is in use, when the second telescopic section 102 is extended from the first telescopic section 101, the leg 2 will rotate to a vertical state, and the bottom end of the elastic rod 3 will press against the bottom of the notch 201 on the leg 2, so as to vertically fix the leg 2, so as to realize automatic support and fixation of the suspended end of the telescopic belt conveyor body 1, which can greatly improve the overall stability of the device. Even if some heavy objects are transported, the device will not overturn.

[0034] Secondly, when the elastic rod 3 is vertically fixing the leg 2, the bottom end of the elastic rod 3 will be inserted into the through hole 202 at the bottom of the notch 201, and the bottom end of the elastic rod 3 will extend into the through hole 202, thereby forming a limited fixing, which can greatly ensure the stability of the elastic rod 3 vertically fixing the leg 2, thereby ensuring the stability of the leg 2 supporting the suspended end of the telescopic belt conveyor body 1;

[0035] Finally, during the process of the second telescopic section 102 being retracted to the first telescopic section 101, the round head end block 403 on the inclined surface of the mounting plate 4 will contact the top block 203 and push the top block 203 forward a short distance. At this time, the top block 203 pushes the bottom end of the elastic rod 3 outward to make it disengage from the through hole 202. Then the roller 402 at the bottom of the inclined surface of the mounting plate 4 will contact the leg 2 in advance to limit the leg 2, causing the leg 2 to rotate and the elastic rod 3 to retract. When the leg 2 rotates to a certain extent, the top of the inclined surface of the mounting plate 4 The roller shaft 402 at the bottom limits the leg 2, allowing the leg 2 to continue to rotate until the second telescopic section 102 is completely contracted. At this time, the leg 2 is horizontally attached to the bottom of the second telescopic section 102, thereby realizing the automatic storage effect of the leg 2 and improving the convenience of storing the leg 2. In addition, under the limited cooperation of the roller shaft 402, when the second telescopic section 102 is extended, the leg 2 will slowly rotate downward, so that the elastic rod 3 can stably extend to support the leg 2, which can prevent the end of the elastic rod 3 from detaching from the leg 2.
