Description
Technical Field
[0001] This utility model relates to the field of conveyor technology, specifically a self-propelled telescopic belt conveyor. Background Technology
[0002] Concrete construction is a crucial step in the construction of special engineering structures such as spillways. Because these structures need to withstand the impact of high-speed water flow and long-term wear, there are high requirements for the strength and impact resistance of the concrete. To meet these requirements, the concrete type usually selected has a very low slump. Therefore, it is difficult to transport such high-viscosity concrete mixtures by traditional pumping methods during construction, especially in the narrow and complex environment inside the spillway.
[0003] The existing method of conveying concrete in the flood discharge tunnel is mainly through simple conveyor belts. However, when simple conveyor belts are placed in the flood discharge tunnel, they not only occupy a lot of space, but are also difficult to move after a section is completed. Moreover, the simple conveyor belts cannot be adjusted to deliver concrete to different destinations during the construction process, resulting in low construction efficiency. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model proposes the following technical solution: A self-propelled telescopic belt conveyor includes a walking chassis module, a telescopic belt conveyor assembly mounted on the walking chassis module, and a lifting module rotatably mounted on the walking chassis module. One end of the lifting module is rotatably connected to the telescopic belt conveyor assembly to drive the telescopic belt conveyor assembly to rotate on the walking chassis module.
[0005] Furthermore, the telescopic belt conveyor assembly includes a fixed truss, truss two, truss three, and a head section truss. The fixed truss serves as the telescopic and lifting fixed section of the telescopic belt conveyor assembly. The fixed truss is rotatably connected to the traveling chassis module. Truss two is slidably installed inside the fixed truss via guide rails. Truss three is slidably installed inside truss two via guide rails. Truss three is slidably connected to the head section truss via guide rails. The fixed truss, truss two, truss three, and head section truss can slide relative to each other to extend or retract.
[0006] Furthermore, the telescopic belt conveyor assembly also includes a conveyor belt for conveying materials, which is disposed within the fixed truss, truss two, truss three, and head truss.
[0007] Furthermore, the telescopic belt conveyor assembly is provided with multiple belt brackets for limiting the position of the conveyor belt. The belt brackets are in contact with the conveyor belt. The multiple belt brackets are respectively set on the fixed truss, truss two, truss three, and head section truss. The belt brackets are used to bear the weight of the material on the conveyor belt.
[0008] Furthermore, the telescopic belt conveyor assembly includes a head section roller, which is located at the end of the head section truss away from the fixed truss, and the head section roller is used to change the movement trajectory of the conveyor belt.
[0009] Furthermore, the telescopic belt conveyor assembly includes multiple tensioning screws, which are rotatably mounted on the fixed truss, truss two, truss three, and head section truss, respectively. A redirecting roller is rotatably mounted on the tensioning screw, and the redirecting roller contacts the conveyor belt. The tensioning screw and the redirecting roller are used to adjust the tension of the conveyor belt.
[0010] Furthermore, the telescopic belt conveyor assembly is provided with multiple sets of steel rope telescopic components. The steel rope telescopic components are used to control the telescopic belt conveyor assembly to extend and retract. There are a total of three sets of steel rope telescopic components in the telescopic belt conveyor assembly, which are respectively installed on the fixed truss, truss two, and truss three.
[0011] Furthermore, a hydraulic station is fixedly installed on the walking chassis module. The hydraulic station provides extension and retraction power to the support module through hydraulic oil. The support module includes a fixed frame, an intermediate frame, and a movable frame. The fixed frame is rotatably connected to the walking chassis module, the fixed frame is slidably connected to the intermediate frame, the intermediate frame is slidably connected to the movable frame, and the movable frame is rotatably connected to one end of the telescopic belt conveyor assembly. A hydraulic cylinder is fixedly installed inside the intermediate frame, and the movable end of the hydraulic cylinder is fixedly connected to the movable frame. The hydraulic cylinder is used to drive the movable frame to slide on the intermediate frame.
[0012] Furthermore, rotating pulleys are provided on both sides of the intermediate frame, and sliding steel cables are provided on the rotating pulleys. One point of the sliding steel cable is fixedly connected to the movable frame, and the other point of the sliding steel cable is fixedly connected to the fixed frame.
[0013] Furthermore, the walking chassis module includes a chassis one, a slewing support shaft rotatably mounted on the bottom of the chassis one, a support hinge fixedly mounted on the slewing support shaft, a rotating shaft rotatably mounted on the support hinge, a chassis two fixedly mounted on the rotating shaft, and multiple rear tires rotatably mounted on the chassis two.

[0014] Furthermore, a positioning shaft for limiting is threaded onto the support hinge, and the positioning shaft contacts the chassis and can be used to limit the position between the support hinge and the chassis.
[0015] Furthermore, a front wheel bracket is rotatably mounted on the chassis, and a front tire is rotatably mounted on the front wheel bracket. The front tire is used to support the movement of the chassis module.
[0016] Furthermore, a front support shaft is provided at the connection between the front wheel bracket and the chassis, and the front support shaft is used to drive the front wheel bracket to rotate.
[0017] Compared with the prior art, the advantages of this utility model are: (1) This device allows the fixed truss, truss two, truss three and head section truss in the telescopic belt conveyor assembly to slide synchronously to extend and retract, so that the device can cover a larger area when conveying materials, and shrink to the minimum state when transporting or moving, so as to facilitate movement in a limited space and expand the applicability of the device; (2) This device allows the front support shaft to drive the front wheel bracket and the front tire to rotate, so that the device can swing at a certain angle when conveying materials, so as to facilitate the device to convey materials to a designated position in the tunnel and effectively reduce the movement time of the device; (3) This device allows the device to move on steep slopes or special environments when moving, through the rotating shaft and the slewing support shaft set on the chassis one, so as to facilitate the user to move the position of the device.

Detailed Implementation
[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0031] like Figure 1 As shown, a self-propelled telescopic belt conveyor includes a walking chassis module 101, on which a telescopic belt conveyor assembly 103 is mounted. The tail end of the walking chassis module 101 and the telescopic belt conveyor 103 are hinged by a pin. A lifting module 102 is rotatably mounted on the walking chassis module 101. One end of the lifting module 102 is rotatably connected to the telescopic belt conveyor assembly 103 to drive the rotation of the telescopic belt conveyor assembly 103 on the walking chassis module 101. The lifting module 102 and the telescopic belt conveyor assembly 103 are connected by a pin hinge.
[0032] like Figure 1 , Figure 2 , Figure 9 , Figure 10As shown, the walking chassis module 101 includes a chassis 201, on which a secondary counterweight box is provided. The secondary counterweight box is located at the connection between the walking chassis module 101 and the telescopic belt conveyor assembly 103 to prevent the telescopic belt conveyor assembly 103 from shaking or tilting. A slewing support shaft 202 is rotatably mounted on the bottom of the chassis 201, and a support lug 208 is fixedly mounted on the slewing support shaft 202. The slewing support shaft 202 is connected to the chassis 201, and the support lug 208 is connected to the bottom of the support. A positioning shaft 203 for limiting the position is threaded onto the hinge 208. The positioning shaft 203 contacts the chassis 201. The positioning shaft 203 can be used to limit the position between the hinge 208 and the chassis 201. When the hinge 208 does not need to rotate relative to the chassis 201, the positioning shaft 203 contacts the chassis 201 to limit the position of the hinge 208. When the hinge 208 needs to rotate on the chassis 201, the positioning shaft 203 can be disengaged from the chassis 201.
[0033] like Figure 9 , Figure 10 As shown, a rotating shaft 207 is rotatably mounted on the supporting hinge 208. A chassis 205 is fixedly mounted on the rotating shaft 207. Multiple rear tires 204 are rotatably mounted on the chassis 205. Each rear tire 204 is equipped with a wheel-side drive motor to provide power. A main counterweight box 206 is provided on the chassis 205 to lower the center of gravity of the walking chassis module 101. By adjusting the angle of the rotating shaft 207 on the supporting hinge 208, the rear tires 204 can always maintain contact with the ground, adapting to some working environments with slopes or special conditions. The multiple rear tires 204 are connected by a steering linkage. The connection is made so that the rear tires 204 rotate in the same direction on the main counterweight box 206. A steering hydraulic cylinder 214 is rotatably mounted on the main counterweight box 206. The moving end of the steering hydraulic cylinder 214 is set on any one of the rear tires 204. The steering hydraulic cylinder 214 is used to drive the rear tires 204 to rotate relative to the main counterweight box 206. This allows the device to turn or adjust its position. When the device needs to swing left or right, it can swing around the axis of the slewing support shaft 202. When moving forward or backward, the pivot shaft 207 and the support hinge 208 are fixed.
[0034] like Figure 9 and Figure 10As shown, the walking chassis module 101 includes a front wheel bracket 210, which is rotatably connected to the chassis 201. A hydraulic slewing bearing is provided between the wheel bracket 210 and the chassis 201 to drive the front wheel bracket 210 to rotate. The front wheel brackets 210 are symmetrically arranged on the chassis 201. The connection between the front wheel bracket 210 and the chassis 201 is located at the end away from the connection between the telescopic belt conveyor assembly 103 and the walking chassis module 101. A front support shaft 212 is provided at the connection between the front wheel bracket 210 and the chassis 201. The front support shaft 212 is used to drive the front wheel bracket 210 to rotate. The front support shaft 212 is also a hydraulic slewing bearing, which is driven by hydraulic power or controlled by a motor.
[0035] like Figure 9 and Figure 10 As shown, a front tire 211 is rotatably mounted on the front wheel bracket 210. The front tire 211 supports the movement of the walking chassis module 101. When swinging or walking is required, the front tire 211 is rotated to the tangent of its rotation radius or parallel to the axis of the equipment. A drive motor 213 is provided on the front wheel bracket 210. The drive motor 213 is connected to the front tire 211 through a drive chain. When the drive motor 213 is working, it drives the front tire 211 to rotate. When the device needs to reciprocate and swing to convey materials within a certain range, the front support shaft 212 can drive the front wheel bracket 210 to rotate relative to the chassis 201, allowing the front wheel bracket 210 to rotate a predetermined degree, so that the chassis 201 and the front tire 211 reach a certain distance. Figure 10 In this state, when the drive motor 213 is started, the chassis 201 can rotate around the axis of the rotary support shaft 202. The purpose of the swing is to allow the device to transport materials within a certain range during continuous operation.
[0036] When this device moves forward or backward, the front tire 211 is rotated to a state parallel to the chassis 201 via the front support shaft 212. Then, forward and backward movement is achieved by the front tire 211 and the rear tire 204 simultaneously rotating in both directions. The power source for the rotation of the rear tire 204 is a wheel-side drive motor. When turning, the rear tire 204 is driven to turn by the steering hydraulic cylinder 214 in the rear tire 204 and the steering linkage. When this device swings left and right, the rear tire 204 is stationary on the ground. The front tire 211 is driven to rotate by the hydraulic rotary support, allowing the front tire 211 to rotate to fixed positions on both sides. The front tire 211 swings left and right by the simultaneous forward and reverse rotation of the drive motor 213. Note that here, the entire chassis 201 and the front tire 211 reciprocate around the rotary support shaft 202.
[0037] like Figure 1 , Figure 9 , Figure 11As shown, a hydraulic station 209 is fixedly installed on the chassis module 101. The hydraulic station 209 provides extension and retraction power to the lifting module 102 via hydraulic oil. The hydraulic station 209 can also provide power to the hydraulic slewing support to drive the front wheel bracket 210 to rotate. The hydraulic station 209 can also provide power to the steering hydraulic cylinder 214 to drive the rear tire 204 to rotate relative to the main counterweight box 206. The lifting module 102 includes a fixed frame 1023, an intermediate frame 1022, and a movable frame 1021. The fixed frame 1023 is connected to the chassis module 101. The fixed frame 1023 is rotatably connected to the intermediate frame 1022, and the intermediate frame 1022 is slidably connected to the movable frame 1021. The movable frame 1021 is rotatably connected to one end of the telescopic belt conveyor assembly 103. A hydraulic cylinder 1024 is fixedly installed inside the intermediate frame 1022, and the moving end of the hydraulic cylinder 1024 is fixedly connected to the movable frame 1021. The hydraulic cylinder 1024 is used to drive the movable frame 1021 to slide on the intermediate frame 1022. Rotating pulleys 1025 are also provided on both sides of the intermediate frame 1022. A sliding steel cable 1026 is provided on the rotating pulley 1025. One point of the sliding steel cable 1026 is fixedly connected to the movable frame 1021, and the other point of the sliding steel cable 1026 is fixedly connected to the fixed frame 1023. When the hydraulic cylinder 1024 drives the movable frame 1021 to move relative to the intermediate frame 1022, the intermediate frame 1022 will also move synchronously relative to the intermediate frame 1022, carrying the fixed frame 1023 with it through the sliding steel cable 1026. After the hydraulic cylinder 1024 is started, it can move the movable frame 1021 relative to the intermediate frame 1022 through the sliding steel cable 1026. 1. The intermediate frame 1022 and the fixed frame 1023 have a synchronous telescopic function, thereby controlling the angle of the telescopic belt conveyor assembly 103 relative to the ground. The angle range of the telescopic belt conveyor assembly 103 relative to the ground is zero to twenty-two degrees. It is worth noting that the hydraulic cylinder 1024 is the power source for the displacement of the lifting module 102, while the sliding steel cable 1026 is a device that synchronizes the intermediate frame 1022 and the fixed frame 1023. Its main purpose is to increase the extension height of the telescopic belt conveyor assembly 103 without changing the hydraulic cylinder 1024.
[0038] like Figures 1 to 3 and Figure 5 , Figure 6As shown, the telescopic belt conveyor assembly 103 includes a fixed truss 3021, a second truss 3022, a third truss 3023, and a head section truss 3024. The fixed truss 3021 serves as the telescopic and lifting fixed section of the telescopic belt conveyor assembly 103. The fixed truss 3021 is rotatably connected to the walking chassis module 101. The second truss 3022 is slidably installed in the fixed truss 3021 via guide rails. The third truss 3023 is slidably installed in the second truss 3022 via guide rails. The third truss 3023 is slidably connected to the head section truss 3024. The fixed truss 3021, the second truss 3022, the third truss 3023, and the head section truss 3024 can slide relative to each other to extend or retract.
[0039] like Figures 1 to 3 and Figure 5 , Figure 6 As shown, the telescopic belt conveyor assembly 103 also includes a conveyor belt 306 for conveying materials. The conveyor belt 306 is disposed within the fixed truss 3021, the second truss 3022, the third truss 3023, and the head truss 3024. The fixed truss 3021 is provided with a material inlet 302, which is the material entry point for the telescopic belt conveyor assembly 103. The conveyor belt 306 is disposed below the material inlet 302. The conveyor belt 306 is a completely closed conveyor belt within the telescopic belt conveyor assembly 103. An electric roller 3 is disposed within the telescopic belt conveyor assembly 103. 10. The electric roller 310 contacts the conveyor belt 306 to drive the electric roller 310 to convey materials within the telescopic belt conveyor assembly 103. The wrap angle between the electric roller 310 and the conveyor belt 306 must be greater than 150 degrees. The telescopic belt conveyor assembly 103 is also equipped with an expansion roller to limit the wrap angle between the electric roller 310 and the conveyor belt 306. In addition, the expansion roller is equipped with an adjustment device to adjust the belt position and prevent belt deviation. The electric roller 310 is mounted on the fixed truss 3021, and the expansion roller is also mounted on the fixed truss 3021.
[0040] like Figures 1 to 3 and Figures 5 to 7 As shown, the telescopic belt conveyor assembly 103 is provided with multiple belt brackets 313 for limiting the position of the conveyor belt 306. The belt brackets 313 are in contact with the conveyor belt 306. The multiple belt brackets 313 are respectively set on the fixed truss 3021, truss 2 3022, truss 3023 and head section truss 3024. The belt brackets 313 are used to bear the weight of the material on the conveyor belt 306. When the conveyor belt 306 is working, it will rotate with the belt brackets 313. The belt brackets 313 can reduce the wear of the conveyor belt 306 caused by friction.
[0041] like Figures 1 to 3 and Figure 5 , Figure 6 As shown, the telescopic belt conveyor assembly 103 also includes a head section roller 309. The head section roller 309 is located at the end of the head section truss 3024 away from the fixed truss 3021. The head section roller 309 is used to change the movement trajectory of the conveyor belt 306. When material is conveyed to the head section roller 309 via the conveyor belt 306, the material on the conveyor belt 306 will fall out of the telescopic belt conveyor assembly 103 due to gravity. The telescopic belt conveyor assembly 103 is equipped with multiple tensioning screws 303. The tensioning screws 303 are rotatably mounted on the fixed truss 3021, truss 3022, truss 3023, and head truss 3024, respectively. A redirecting roller 304 is rotatably mounted on the tensioning screw 303. The redirecting roller 304 contacts the conveyor belt 306. The tensioning screws 303 and the redirecting roller 304 are used to adjust the tension of the conveyor belt 306. At the same time, the redirecting roller 304 can also correct the belt misalignment problem. The section of the conveyor belt 306 that contacts the redirecting roller 304 does not carry material.
[0042] like Figure 6 , Figure 8 As shown, the telescopic belt conveyor assembly 103 is equipped with multiple sets of steel cable telescopic components. These components control the telescopic movement of the conveyor assembly 103. There are three sets of steel cable telescopic components within the assembly 103, respectively mounted on fixed truss 3021, truss two 3022, and truss three 3023. Each steel cable telescopic component includes a steel cable pulley 308, a secondary connecting block 316, a main connecting block 315, and a steel cable 314. The connection relationship of the steel cable telescopic component mounted on truss three 3023 is as follows: two steel cable pulleys 308 are rotatably connected to truss three 3023, with the two pulleys 308 respectively located at both ends of truss three 3023; the steel cable 314 is mounted on the steel cable pulleys 308; the main connecting block 315 is fixedly connected to truss two 3022; and the secondary connecting block 316 is fixedly connected to the head section truss 3024. The auxiliary connector 316 is fixedly connected to the steel rope 314. Here, it can be seen that one end of the steel rope 314 is connected to the second truss 3022 through the main connector 315. At the same time, the steel rope 314 passes over the front rope pulley 308 on the third truss 3023. After the steel rope pulley 308 is redirected, the other end of the steel rope pulley 308 is connected to the auxiliary connector 316 behind the head section truss 3024. In this way, when the second truss 3022 and the third truss 3023 move relative to each other, the third truss 3023 and the head section truss 3024 can move synchronously.
[0043] The steel cable 314 can drive the first section truss 3024 and the second truss 3022 to move relative to the third truss 3023 through the main connecting block 315 and the auxiliary connecting block 316. In the actual operation, the second truss 3022, the third truss 3023 and the first section truss 3024 will extend and retract synchronously.
[0044] like Figure 6 As shown, a winch reducer 312 is provided on the fixed truss 3021, and a winch drum is provided on the fixed truss 3021. The winch reducer 312 drives the winch drum through a transmission chain, and the winch drum is connected to a steel rope 314 installed on the fixed truss 3021. In this way, the winch reducer 312 can drive the steel rope telescopic assembly on the fixed truss 3021 to work.
[0045] The specific operation is as follows: When the telescopic belt conveyor assembly 103 is telescopic, the steel rope telescopic component on the fixed truss 3021 first operates, while the winch reducer 312 drives the winch drum to rotate via the transmission chain. This allows the steel rope 314 in the steel rope telescopic component on the fixed truss 3021 to rotate clockwise on the winch drum. When the winch drum rotates clockwise, the steel rope 314 is redirected by the steel rope pulley 308 and pulls the second truss 3022 out. When the second truss 3022 moves relative to the fixed truss 3021, the steel rope telescopic component on the second truss 3022 will synchronously drive the third truss 3023 to move. The steel rope telescopic component on the third truss 3023 will then drive the first section truss 3024 to move. This allows the telescopic belt conveyor assembly 103 to telescopically move.
[0046] like Figure 6 , Figure 8 As shown, the steel cable telescopic assembly (the same steel cable telescopic assembly is described here) is installed on truss 2 3022. The steel cable pulley 308 is rotatably installed at both ends of truss 2 3022. The main connector 315 on this steel cable telescopic assembly is fixedly connected to the fixed truss 3021. Similarly, the auxiliary connector 316 on this steel cable telescopic assembly is fixedly connected to truss 3 3023. One end of the steel cable 314 is set on the main connector 315 in the fixed truss 3021. The steel cable 314 is redirected from above the front pulley 308 in steel truss 2 3022 and connected from below to the auxiliary connector 316 at the rear of truss 3 3023.
[0047] When the telescopic belt conveyor assembly 103 needs to be extended to its longest position, multiple steel rope telescopic components within the telescopic belt conveyor assembly 103 operate simultaneously. Among them, the winch drum is driven to rotate by the winch reducer 312, causing the second truss 3022, the third truss 3023, and the first truss section 3024 to slide synchronously. Figure 1 and Figure 2 As shown, when truss 2 3022, truss 3023, and head truss 3024 slide to their limit positions, the telescopic belt conveyor assembly 103 is in its maximum extension state.
[0048] Specific embodiment: When using this device, the operating environment is inside the power station spillway tunnel. This device is used in conjunction with other equipment, so the device needs to transport concrete to a high place or onto the bottom slab. Because the bottom slab reinforcement cage is 1.5 meters high, it is impossible to use other equipment for placement. During the transportation of this device, the telescopic belt conveyor assembly 103 and the traveling chassis module 101 are generally transported separately. When this device is to be used, the telescopic belt conveyor assembly 103 and the traveling chassis module 101 can be transported into the tunnel for assembly.
[0049] During operation, this device uses a winch reducer 312 to drive the winch drum on the fixed truss 3021 to rotate. This, in turn, causes the steel cable telescopic assembly on the fixed truss 3021 to drive the second truss 3022 to move. The steel cable telescopic assembly on the second truss 3022 then synchronously drives the third truss 3023 to move, and the steel cable telescopic assembly on the third truss 3023 in turn drives the first truss section 3024 to move synchronously. This allows the second truss 3022, the third truss 3023, and the first truss section 3024 to move synchronously relative to each other on the fixed truss 30211, thus achieving the telescopic conveyor assembly 103's telescopic function. Simultaneously with the movement of the second truss 3022, the third truss 3023, and the first truss section 3024, the conveyor belt 306 also moves synchronously due to the positional changes of these components. Figure 3 and Figure 5 The state shown is that the conveyor belt 306 is in its extended limit position, while Figure 6 This refers to the state where the conveyor belt 306 is retracted to its limit position. In both of these states, the conveyor belt 306 can complete the conveying work.
[0050] In this device, the electric drum 310 drives the conveyor belt 306. Material is poured onto the conveyor belt 306 through the material inlet 302, and then transported by the conveyor belt 306 to one end of the head truss 3024 where the head drum 309 is located. The conveyor belt 306 then turns back at the head drum 309, where the material falls out of the device due to gravity and enters other equipment or a designated location. This allows for the pouring of concrete into the tunnel walls or directly into the foundation slab. As the pouring process continues, the pouring position changes. Therefore, during the conveying process of this device, the position of the head roller 309 within the tunnel also needs to change. In practical use, if the device needs to swing in place, the front support shaft 212 will drive the front wheel bracket 210 and the front tire 211 to rotate at a certain angle. The purpose of this rotation is to allow the front tire 211 to drive the chassis 201 to rotate around the axis of the rotary support shaft 202. It is worth noting here that... The positioning shaft 203 does not contact the chassis 201, so the chassis 201 is rotatably connected to the support lug 208. At this time, the support lug 208 and the rear tire 204 do not lock the chassis 201 in place. When the chassis 201 swings around the axis of the rotary support shaft 202, the chassis 201 also causes the telescopic belt conveyor assembly 103 to swing as a whole. This achieves the goal of ensuring the material conveying area covered by the telescopic belt conveyor assembly 103. Simultaneously, the hydraulic station 209 can be activated, allowing the hydraulic station 20... 9. The hydraulic cylinder 1024 in the support module 102 is extended by hydraulic oil to move the moving frame 1021, intermediate frame 1022, and fixed frame 1023. This allows the telescopic conveyor assembly 103 to be raised and lowered relative to the traveling chassis module 101. This changes the height of the first section roller 309 on the telescopic conveyor assembly 103 to transport cement to the top of the tunnel. This not only reduces the time workers spend moving the telescopic conveyor assembly 103, but also improves work efficiency.
[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
