Description

Technical Field

[0001] The present invention relates to the technical field of conveyors, and particularly to a self-propelled telescopic belt conveyor. Background Art

[0002] During the construction of special engineering structures such as flood discharge tunnels, concrete construction is a crucial link. Since these engineering structures such as flood discharge tunnels need to withstand the impact of high-speed water flow and long-term wear, there are relatively high requirements for the strength and abrasion resistance of concrete. To meet these requirements, the slump of the generally selected concrete type is usually very low. Therefore, it is difficult to transport such high-consistency concrete mixtures during the construction process through traditional pumping methods, especially in the narrow and complex environment inside the flood discharge tunnel.

[0003] The existing concrete conveying method inside the flood discharge tunnel is mainly through a simple conveying belt. However, when the simple conveying belt is inside the flood discharge tunnel, it not only occupies a large space, but also is difficult to move after a section of construction is completed. Moreover, during the construction process, the simple conveying belt cannot adjust the conveying destination, resulting in low construction efficiency. Summary of the Invention

Detailed implementation manners

[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention 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 only used to explain the present invention and are not used to limit the present invention.

[0032] As Figure 1 shown, a self - moving telescopic belt conveyor includes a traveling chassis module 101. An telescopic belt conveyor assembly 103 is installed on the traveling chassis module 101. The tail of the traveling chassis module 101 and the telescopic belt conveyor 103 are hinged by a pin shaft. A lifting module 102 is rotatably installed on the traveling 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 traveling chassis module 101. The lifting module 102 and the telescopic belt conveyor assembly 103 are connected by a pin shaft hinge.

[0033] As Figure 1 、 Figure 2 、 Figure 9 、 Figure 10As shown, the walking chassis module 101 includes a chassis 201. A secondary counterweight box is provided on the chassis 201. The secondary counterweight box is arranged 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 installed at the bottom of the chassis 201. A support lug 208 is fixedly installed on the slewing support shaft 202. The slewing support shaft 202 is connected to the lower connection support lug 208 of the chassis 201. A positioning shaft 203 for limiting is threadedly installed on the support lug 208. The positioning shaft 203 contacts the chassis 201. The positioning shaft 203 can be used to limit the position between the support lug 208 and the chassis 201. When it is not necessary for the support lug 208 to rotate relative to the chassis 201, the positioning shaft 203 is made to contact the chassis 201 to limit the position of the support lug 208. When it is necessary for the support lug 208 to rotate on the chassis 201, the positioning shaft 203 can be made to disengage from the chassis 201.

[0034] As Figure 9 , Figure 10 shown, a rotating shaft 207 is rotatably installed on the support lug 208. A chassis 205 is fixedly installed on the rotating shaft 207. A plurality of rear tires 204 are rotatably installed on the chassis 205. A wheel side drive motor is provided on the rear tires 204 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 support lug 208, the rear tires 204 can always be in contact with the ground to adapt to some sloping or special working environments. The plurality of rear tires 204 are connected by a steering link. Here, the steering link is used to make the rear tires 204 rotate in the same direction on the main counterweight box 206. A steering hydraulic cylinder 214 is rotatably installed on the main counterweight box 206. The moving end of the steering hydraulic cylinder 214 is arranged on any one of the rear tires 204. The steering hydraulic cylinder 214 is used to drive the rear tire 204 to rotate relative to the main counterweight box 206. In this way, the device can be turned or its position adjusted. When the device needs to swing left and right, it can swing around the axis of the slewing support shaft 202. When moving forward and backward, the rotating shaft 207 and the support lug 208 are fixed.

[0035] As 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, and a hydraulic slewing support is arranged between the wheel bracket 210 and the chassis 201 to drive the front wheel bracket 210 to rotate. The front wheel bracket 210 is symmetrically arranged on the chassis 201, and the connection between the front wheel bracket 210 and the chassis 201 is arranged at an end away from the connection between the telescopic belt conveyor assembly 103 and the walking chassis module 101. A front support shaft 212 is arranged at the connection between the front wheel bracket 210 and the chassis 201, and 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 support, which is driven by hydraulic pressure or controlled by a motor.

[0036] like Figure 9 and Figure 10 As shown, the front wheel bracket 210 is rotatably mounted with a front tire 211, and the front tire 211 is used to support the walking chassis module 101 to move. 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. The front wheel bracket 210 is provided with a driving motor 213, and the driving motor 213 is connected to the front tire 211 through a driving chain. The driving motor 213 drives the front tire 211 to rotate when working. When the device needs to perform reciprocating swinging to transport materials within a certain range, the front support shaft 212 can drive the front wheel bracket 210 to rotate relative to the chassis 201, and the front wheel bracket 210 is rotated by a predetermined degree, so that the chassis 201 and the front tire 211 reach Figure 10 In this state, when the driving motor 213 is started, the chassis 201 can rotate around the axis of the rotary support shaft 202, and the purpose of the swing is to allow the device to transport materials within a certain range when it continues to work.

[0037] When the device moves forward or backward, the front tire 211 is rotated to a state parallel to the chassis 201 through the front support shaft 212, and then the front tire 211 and the rear tire 204 are simultaneously and synchronously moved forward and backward. The power source of the rear tire 204 is the wheel-side drive motor. When turning, the steering hydraulic cylinder 214 and the steering connecting rod in the rear tire 204 drive the rear tire 204 to turn. When the device swings left and right, the rear tire 204 is stationary on the ground, and the front tire 211 is driven to rotate by the hydraulic slewing support, so that the front tire 211 rotates to both sides to a fixed position, and the front tire 211 is driven by the drive motor 213 to swing left and right. Note that here the entire chassis 201 and the front tire 211 reciprocate around the slewing support shaft 202.

[0038] like Figure 1 , Figure 9 , Figure 11As shown, a hydraulic station 209 is fixedly installed on the walking chassis module 101. The hydraulic station 209 provides telescopic power for the lifting module 102 through hydraulic oil. The hydraulic station 209 can also provide power for the hydraulic slewing bearing to drive the front wheel bracket 210 to rotate. The hydraulic station 209 can also provide power for 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 moving frame 1021. The fixed frame 1023 is rotatably connected to the walking chassis module 101. The fixed frame 1023 is slidably connected to the intermediate frame 1022. The intermediate frame 1022 is slidably connected to the moving frame 1021. The moving 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. The moving end of the hydraulic cylinder 1024 is fixedly connected to the moving frame 1021. The hydraulic cylinder 1024 is used to drive the moving 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 arranged on the rotating pulley 1025. A point on the sliding steel cable 1026 is fixedly connected to the moving frame 1021. The other point of the sliding steel cable 1026 is fixedly connected to the fixed frame 1023. When the hydraulic cylinder 1024 drives the moving frame 1021 to move relative to the intermediate frame 1022, the intermediate frame 1022 will also drive the fixed frame 1023 to move synchronously relative to the intermediate frame 1022 through the sliding steel cable 1026. After the hydraulic cylinder 1024 is started, the functions of synchronously telescoping the moving frame 1021, the intermediate frame 1022, and the fixed frame 1023 can be achieved through the sliding steel cable 1026, so as to control 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 from zero to twenty-two degrees. It should be noted here that the hydraulic cylinder 1024 is the power source for the displacement of the lifting module 102, and the sliding steel cable 1026 is a device for synchronizing 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 stroke of the hydraulic cylinder 1024.

[0039] As 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 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 through a guide rail. The third truss 3023 is slidably installed in the second truss 3022 through a guide rail. The third truss 3023 is slidably connected to the head truss 3024. The fixed truss 3021, the second truss 3022, the third truss 3023, and the head truss 3024 can slide relative to each other for extension or contraction.

[0040] As Figures 1 to 3 with Figure 5 、 Figure 6 As shown, the telescopic belt conveyor assembly 103 further includes a conveyor belt 306 for conveying materials. The conveyor belt 306 is arranged inside the fixed truss 3021, the second truss 3022, the third truss 3023, and the head truss 3024. A material inlet 302 is provided on the fixed truss 3021. The material inlet 302 is the material inlet of the telescopic belt conveyor assembly 103. The conveyor belt 306 is arranged below the material inlet 302. The conveyor belt 306 is a complete closed conveyor belt inside the telescopic belt conveyor assembly 103. An electric roller 310 is arranged inside the telescopic belt conveyor assembly 103. The electric roller 310 is in contact with the conveyor belt 306 to drive the electric roller 310 to convey materials inside the telescopic belt conveyor assembly 103. The wrap angle between the electric roller 310 and the conveyor belt 306 needs to be greater than 150 degrees. An idler roller is also provided on the telescopic belt conveyor assembly 103 to limit the wrap angle between the electric roller 310 and the conveyor belt 306. In addition, an adjusting device is provided on the idler roller to adjust the position of the belt to prevent the belt from running off track. The electric roller 310 is arranged on the fixed truss 3021, and the idler roller is also arranged on the fixed truss 3021.

[0041] As Figures 1 to 3 with Figures 5 to 7 As shown, a plurality of belt brackets 313 for limiting the position of the conveyor belt 306 are arranged inside the telescopic belt conveyor assembly 103. The belt brackets 313 are in contact with the conveyor belt 306. The plurality of belt brackets 313 are respectively arranged on the fixed truss 3021, the second truss 3022, the third truss 3023, and the head truss 3024. The belt brackets 313 are used to bear the weight of the materials on the conveyor belt 306. The conveyor belt 306 will drive the belt brackets 313 to rotate during operation, and the belt brackets 313 can reduce the loss of the conveyor belt 306 caused by friction.

[0042] As Figures 1 to 3 with Figure 5 、Figure 6 As shown, a head section drum 309 is further provided inside the telescopic belt conveyor assembly 103. The head section drum 309 is arranged at one end of the head section truss 3024 away from the fixed truss 3021. The head section drum 309 is used to change the movement track of the conveyor belt 306. When the material on the conveyor belt 306 is conveyed to the head section drum 309, the material on the conveyor belt 306 will fall out of the telescopic belt conveyor assembly 103 due to gravity. A plurality of tensioning screws 303 are arranged on the telescopic belt conveyor assembly 103. The tensioning screws 303 are respectively rotatably installed on the fixed truss 3021, the second truss 3022, the third truss 3023, and the head section truss 3024. A redirecting roller 304 is rotatably installed on the tensioning screw 303. The redirecting roller 304 is in contact with the conveyor belt 306. The tensioning screw 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 adjust the problem of belt deviation. And a section of the conveyor belt 306 in contact with the redirecting roller 304 does not carry materials.

[0043] As Figure 6 、 Figure 8 As shown, a plurality of steel rope telescopic assemblies are arranged inside the telescopic belt conveyor assembly 103. The steel rope telescopic assemblies are used to control the telescoping of the telescopic belt conveyor assembly 103. And a total of three groups of steel rope telescopic assemblies are arranged inside the telescopic belt conveyor assembly 103. The steel rope telescopic assemblies are respectively arranged on the fixed truss 3021, the second truss 3022, and the third truss 3023. The steel rope telescopic assembly includes a steel rope wheel 308, a secondary connecting block 316, a main connecting block 315, and a steel rope 314. The connection relationship of the steel rope telescopic assembly arranged on the third truss 3023 is as follows. Two steel rope wheels 308 are rotatably connected to the third truss 3023. The two steel rope wheels 308 are respectively arranged at both ends of the third truss 3023. The steel rope 314 is arranged on the steel rope wheel 308. The main connecting block 315 is fixedly connected to the second truss 3022. The secondary connecting block 316 is fixedly connected to the head section truss 3024. The secondary connecting block 316 is fixedly connected to the steel rope 314. Here, it can be regarded that one end of the steel rope 314 is connected to the second truss 3022 through the main connecting block 315. At the same time, the steel rope 314 passes over the front rope wheel 308 on the third truss 3023. After the steel rope wheel 308 is redirected in this way, the other end of the steel rope wheel 308 is connected to the secondary connecting block 316 behind the head section truss 3024. In this way, when the second truss 3022 and the third truss 3023 perform relative movement, the third truss 3023 and the head section truss 3024 can move synchronously.

[0044] The steel rope 314 can drive the head section truss 3024 and the second truss 3022 to move relative to the third truss 3023 through the main connecting block 315 and the secondary connecting block 316. And in the specific working process, the second truss 3022, the third truss 3023, and the head section truss 3024 will synchronously telescope.

[0045] As Figure 6 shown, a hoist speed reducer 312 is provided on the fixed truss 3021, a hoist drum is provided on the fixed truss 3021, the hoist speed reducer 312 drives the hoist drum through a transmission chain, and the hoist drum is connected to a steel rope 314 installed on the fixed truss 3021. In this way, the hoist speed reducer 312 can drive the steel rope telescopic assembly on the fixed truss 3021 to work.

[0046] Specifically, when the telescopic belt conveyor assembly 103 is telescoping, first, the steel rope telescopic assembly on the fixed truss 3021 works, and the hoist speed reducer 312 drives the hoist drum to rotate through a transmission chain. In this way, the steel rope 314 in the steel rope telescopic assembly on the fixed truss 3021 can rotate clockwise on the hoist drum. When the hoist drum rotates clockwise, the steel rope 314 is redirected by the steel rope wheel 308 and then pulls the second truss 3022 to extend. When the second truss 3022 moves relative to the fixed truss 3021, at this time, the steel rope telescopic assembly on the second truss 3022 will synchronously drive the third truss 3023 to move, and the steel rope telescopic assembly on the third truss 3023 will drive the head truss 3024 to move. In this way, the telescopic belt conveyor assembly 103 can be telescoped.

[0047] As Figure 6 、 Figure 8 shown, for the steel rope telescopic assembly provided on the second truss 3022 (here is the introduction of the same steel rope telescopic assembly provided on the second truss 3022), the steel rope wheel 308 is rotatably installed at both ends of the second truss 3022. The main connecting block 315 on this steel rope telescopic assembly is fixedly connected to the fixed truss 3021. Similarly, the secondary connecting block 316 on this steel rope telescopic assembly is fixedly connected to the third truss 3023. One end of the steel rope 314 is provided on the main connecting block 315 in the fixed truss 3021, and the steel rope 314 is redirected above the front rope wheel 308 in the second steel truss 3022 through the steel rope wheel 308 and is connected to the secondary connecting block 316 behind the third truss 3023 from below.

[0048] When the telescopic belt conveyor assembly 103 needs to extend to the longest state, multiple steel rope telescopic assemblies in the telescopic belt conveyor assembly 103 work simultaneously. Among them, the hoist speed reducer 312 drives the hoist drum to rotate, so that the second truss 3022, the third truss 3023, and the head truss 3024 slide synchronously. As Figure 1 and Figure 2 shown, when the second truss 3022, the third truss 3023, and the head truss 3024 slide to the limit position, it is the maximum extension state of the telescopic belt conveyor assembly 103.

[0049] Specific Embodiment: When this device is in use, the operating environment is inside the flood discharge tunnel of a power station. This device is used in conjunction with other equipment. Therefore, what this device needs to do is to convey concrete to a high place or onto the bottom slab for placing. Since the steel reinforcement cage of the bottom slab is 1.5 meters high and other equipment cannot be used for placing, during the transportation process of this device, generally, the telescopic belt conveyor assembly 103 and the walking chassis module 101 are transported separately. When this device is to be used, the telescopic belt conveyor assembly 103 and the walking chassis module 101 of this device can be transported into the tunnel for assembly.

[0050] When this device is working, the hoist reducer 312 drives the hoist drum on the fixed truss 3021 to rotate, thereby enabling the steel rope telescopic assembly on the fixed truss 3021 to drive the truss two 3022 to move. The steel rope telescopic assembly on the truss two 3022 will synchronously drive the truss three 3023 to move, and the steel rope telescopic assembly on the truss three 3023 will drive the head truss 3024 to move synchronously. In this way, the truss two 3022, the truss three 3023, and the head truss 3024 will perform synchronous telescopic movement relative to the fixed truss 30211, thereby enabling the telescopic belt conveyor assembly 103 to achieve the purpose of telescoping. While the truss two 3022, the truss three 3023, and the head truss 3024 are moving, the conveyor belt 306 will also move synchronously due to the position changes during the movement of the truss two 3022, the truss three 3023, and the head truss 3024. Figure 3 And Figure 5 The state shown in Figure 6 is the state where the conveyor belt 306 extends to the extreme position, and

[0051] The operation of this device is carried out by driving the conveyor belt 306 with the electric roller 310. The material is poured onto the conveyor belt 306 at the material inlet 302, and then conveyed by the conveyor belt 306 to one end of the head section truss 3024 where there is a head section roller 309. After that, the conveyor belt 306 will turn back at the head section roller 309, and at the head section roller 309, the material will fall out of this device due to gravity and enter other equipment or a designated position. Through other equipment, the inner wall of the tunnel is concreted or the floor concrete is directly poured. During the continuous pouring process, the pouring position will change. Therefore, during the conveying process of this device, the position of the head section roller 309 of this device in the tunnel also needs to change. So, in the specific use process, if this device needs to swing in place, the front support shaft 212 will be driven to rotate the front wheel bracket 210 and the front tire 211 by a certain angle. The purpose of this rotation is to let the front tire 211 drive the chassis 201 to rotate around the axis of the slewing support shaft 202. It should be noted here that at this time, the positioning shaft 203 does not contact the chassis 201. Therefore, the chassis 201 and the support hinge ear 208 are rotatably connected. At this time, the support hinge ear 208 and the rear tire 204 will not lock the chassis 201 to swing. When the chassis 201 swings around the axis of the slewing support shaft 202, the chassis 201 will also drive the telescopic belt conveyor assembly 103 as a whole to swing. In this way, the problem of the conveying material coverage area of the telescopic belt conveyor assembly 103 can be achieved. At the same time, the hydraulic station 209 can also be started to let the hydraulic station 209 drive the hydraulic cylinder 1024 in the lifting module 102 to extend through hydraulic oil, so that the moving frame 1021, the intermediate frame 1022, and the fixed frame 1023 move. In this way, the telescopic belt conveyor assembly 103 can be lifted relative to the traveling chassis module 101 with the telescopic belt conveyor assembly 103. In this way, the height of the head section roller 309 on the telescopic belt conveyor assembly 103 can be changed to convey cement to the top of the tunnel, which can not only reduce the time for workers to move the telescopic belt conveyor assembly 103 and improve work efficiency.

[0052] The above is only a preferred embodiment of the present invention and is not used to limit the protection scope of the present invention.
