Description

Technical Field

[0001] The utility model belongs to the technical field of integrated wet shotcrete machine devices, and particularly relates to a transportation and fixing structure for a wet shotcrete machine device. Background Technique

[0002] A wet shotcrete machine is a concrete spraying device, mainly used for the shotcrete construction of underground projects such as tunnels, culverts, subways, and foundation pit support. The wet shotcrete machine adopts a hydraulic pumping method to transport the concrete mixture through a pipeline to the nozzle. At the nozzle, the concrete mixture is fully mixed with high-pressure water mist and sprayed onto the working surface at a certain speed. The hydraulic pumping pressure of the traditional wet shotcrete machine is provided by an air compressor. A separate place needs to be provided on-site to place the air compressor. The air storage tank and the air compressor itself equipped with a group of air compressors occupy a lot of space, and separate wires need to be connected to it. When there are many wires, it is easy to cause mess on-site, and at the same time, multiple wires increase the risk of electricity use. When the wet shotcrete machine moves and sprays inside the foundation pit, when it exceeds the wire length, the air compressor equipment needs to be moved, resulting in low construction efficiency. At the same time, when the air compressor pipeline is too long, it is easy for the pipeline to bend, resulting in excessive resistance when the air compressor operates, causing the pipeline to burst.

[0003] In order to solve the above technical problems, the inventor designed an integrated wet shotcrete machine device, which integrates the equipment used for wet shotcrete operations on the traveling mechanism. However, due to the vast construction site and being in the infrastructure construction stage, the integrated wet shotcrete machine device cannot move to some sites by itself and needs to be transported by a transport flatbed. The existing transport flatbed lacks a fixing structure for the integrated wet shotcrete machine device, and it is easy to shake during transportation, resulting in collision damage or loosening of the connections of the equipment. Content of the Utility Model

[0004] In order to facilitate the stable transportation of the entire integrated wet shotcrete machine device, the utility model provides a transportation and fixing structure for a wet shotcrete machine device.

[0005] The technical solution adopted by the utility model is a transportation and fixing structure for a wet shotcrete machine device, including a U-shaped clamp, a round tube, a binding rope, and a hanging hole on the transport flatbed. The U-shaped clamp is fixedly connected to the traveling mechanism of the wet shotcrete machine device in an inverted state, at the bottom of the mounting plate of the traveling mechanism. The round tube is rotatably connected to the U-shaped clamp. One end of the round tube extends out of the U-shaped clamp and is locked by an anti-rotation device. Two binding ropes are used. They pass through the space between the round tube and the U-shaped clamp and the hanging hole in a staggered manner up and down on one side to lock the traveling mechanism on the transport flatbed.

[0006] Further, the above anti-rotation device includes a ratchet and a ratchet pawl. The ratchet is fixedly connected to the left end of the round tube, and the ratchet pawl used in cooperation with the ratchet is rotatably connected to the U-shaped clamp and the ratchet pawl can be lapped on the ratchet teeth of the ratchet.

[0007] Further, on both sides of a section of the above-mentioned circular tube located inside the U-shaped clamp, limit plates are provided, and the limit plates are fixedly connected to the circular tube by welding. A through hole is radially provided at the right end of the circular tube.

[0008] Further, multiple pairs of the above-mentioned U-shaped clamps and circular tubes are used and are respectively arranged on the front and rear sides of the bottom of the mounting plate.

[0009] Further, triangular clamps are provided on both sides of the bottom of the traveling wheels of the above-mentioned traveling mechanism.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: A transportation fixing structure composed of a U-shaped clamp, a circular tube, a binding rope, a hanging hole, and a triangular clamp is provided, which facilitates and stably connects the traveling mechanism to the transportation trolley, avoiding shaking during transportation. The rotatable circular tube can act as a pulley during the binding process, facilitating the sliding of the binding rope and making the binding tighter. After binding, it is locked by an anti-rotation mechanism, which can further improve the binding stability and ensure that the integrated wet shotcreting machine device is transported to the destination intact.

[0027] Among them, the traveling mechanism 1 includes a mounting plate 101 and traveling wheels 102. The mounting plate 101 includes a frame-shaped mounting skeleton and an iron plate fixedly connected to the mounting skeleton by welding. The support is stable and reliable. Two rows of traveling wheels 102 are installed on the left and right of the mounting plate 101. The left row of traveling wheels 102 is rotatably connected to the left rotating shaft. The left rotating shaft is fixedly connected to the stacked strip-shaped shock-absorbing spring plates through U-shaped bolts. The two ends of the stacked strip-shaped shock-absorbing spring plates are connected to the two downwardly protruding connecting ears of the left wheel frame 103. The left wheel frame 103 is rotatably connected to the bottom of the mounting plate 101 through a rotating mechanism. The traveling mechanism adopts two rows of traveling wheels, and the traveling is stable and reliable. Moreover, during the use process, due to the elastic buffering effect of the tires, it can also play a role in noise reduction and vibration reduction; the left wheel frame is connected to the mounting plate through a rotating mechanism, which is convenient for the steering transition during the trailer movement process, improves the traveling stability, and plays a role in protecting the tires, avoiding accelerated tire wear caused by excessive turning; the hitch structure 4 is hitched on the left wheel frame 103, and the hitch structure is hitched on the left wheel frame, which is convenient for the traveling to cooperate with the turning.

[0028] Among them, the hanging structure 4 includes a hanging head 401 and an isosceles triangular frame 402. The hanging head 401 is installed at one corner of the triangular frame 402. The other two corners of the triangular frame 402 are respectively hinged to two hinge ears 403 through connecting single ears 413 perpendicular to the right side of the tripod (i.e., horizontally to the right). The width of the hinge ears is relatively wide, and one end of the stacked strip-shaped shock-absorbing springs is also connected to the right side. This can simplify the structure of the left wheel frame. The two hinge ears 403 are fixedly connected to the left side of the left wheel frame 103. The triangular frame 402 includes a left top triangular plate frame 404 and a hinge ear 405. Two pairs of side reinforcing bars 406 are welded to the two corners on the right side of the left top triangular plate frame 404. Each pair of side reinforcing bars 406 is arranged above and below each corner of the left top triangular plate frame 404. A hinge ear 405 is welded to the right end of each pair of side reinforcing bars 406. A plurality of transverse reinforcing bars 407 are welded between the two pairs of side reinforcing bars 406 to form an isosceles trapezoid structure. Both ends of each transverse reinforcing bar 407 are located between each pair of side reinforcing bars 406 and are fixedly connected at the same time. A plurality of vertical reinforcing bars 408 are welded on the outer side between each pair of side reinforcing bars 406. The hanging structure using a hanging head and an isosceles triangular frame has a frame structure, is light in weight, convenient for hanging, has high rigidity and strength, and good hanging reliability.

The connecting rod 405 is fixedly connected to the left top corner of the left top triangular plate frame 404. By using a hanging cylinder and setting a connecting rod at the rear of the flatbed truck, after the connecting rod is inserted into the hanging cylinder, a pin is used to pass through the hanging cylinder and the connecting rod and then locked, which is convenient for connection and easy to install and disassemble; by using a lifting lug screw for hanging, the hanging is convenient.

[0030] Among them, a grille screen 202 is arranged in the hopper 201 of the wet shotcreting machine 2. The grille screen 202 is connected to a step 204 arranged in the hopper 201 through springs 203 at the four corners. A portal frame 205 is arranged on the grille screen 202. An air-operated vibration pump 206 is fixedly connected to the portal frame 205 and its height is ensured to be higher than the top surface of the hopper 201. The cross-section of the side wall of the mesh hole of the grille screen 202 is an isosceles triangle, and the longitudinal and transverse cross-sections of each grille hole formed by the side walls of the mesh holes are trapezoidal; using a grille screen on the hopper can disperse the concrete fed from the mixing tank and evenly feed it into the lower mixing and feeding mechanism below, improving the spraying quality of the concrete. It is also convenient to filter out too large particles to prevent them from entering the spraying mechanism and damaging the equipment. A portal frame is arranged in the hopper to suspend the air-operated vibration pump above the hopper, avoiding the influence of the concrete moisture in the hopper on the air-operated vibration pump. Using an air-operated vibration pump can avoid the easy damage of the electromagnetic vibration pump in a humid environment. The conventional grille screen adopts a square hole structure composed of round bar steel. Due to long-term use, it is extremely easy for concrete to accumulate on the grille screen, which is not easy to clean and not easy to fall off under vibration. In this application, the side wall of the mesh hole adopts a blade structure, and in combination with vibration, it is extremely easy to make the added concrete fall from the grille screen to the lower mixing and feeding mechanism below, avoiding adhesion to the grille screen after long-term operation, affecting the falling of the concrete and being difficult to clean, and the cleaning is more time-saving and labor-saving. Two handles are arranged on the grille screen, which is convenient for disassembling the grille screen. A downward-sloping high-pressure air jet port is arranged around the spring 203, which can timely blow off the mortar generated on the spring, avoiding affecting the damping performance of the spring. Under the cooperation of spraying and vibration, the mortar is less likely to adhere to the spring and is easier to clean.

[0031] In order to protect the air-operated vibration pump, a protective layer 207 is arranged outside the air-operated vibration pump 206. The protective layer 207 is of a barrel structure. After covering the air-operated vibration pump 206, the bottom is fixedly connected to the portal frame 205. The protective layer 207 includes a waterproof layer 208, a sponge layer 209 and a heat-insulating layer 210 arranged from outside to inside. Two through holes 211 for installing the inlet pipe and outlet pipe of the air-operated vibration pump 206 are arranged at the top of the protective layer 207. The two through holes 211 are embedded with waterproof sleeves 212. The waterproof sleeves 212 are provided with annular grooves 213. The annular grooves 213 are hermetically connected to the protective layer 207. A plurality of sealing rings 214 are arranged in the inner hole of the annular grooves 213. Using a protective layer to cover the air-operated vibration pump can play an effective protective role and prevent the air-operated vibration pump from being damaged. Adopting a three-layer structure of waterproof, sponge and heat insulation can play the roles of waterproofing, elastic protection and isolating too high external temperature. The setting of the waterproof sleeve facilitates the sealed insertion of the inlet pipe and outlet pipe.

[0032] To protect the air pressure distribution valve 216, a shielding rubber sheet 215 is fixed outside the side wall of the hopper 201, and the shielding rubber sheet 215 covers the air pressure distribution valve 216 fixedly installed outside the side wall of the hopper 201; setting the shielding rubber sheet can prevent concrete from splashing onto the air pressure distribution valve, resulting in damage to the pressure distribution valve due to the long-term condensation of cement mortar. Pedals are provided at the bottom sides of the front and rear sides of the hopper 201. Standing on the pedals facilitates the feeding operation. A shielding rubber sheet 215 is also provided at the bottom of the side of the hopper facing the mixing tank. The shielding rubber sheet covers the output pipeline, playing a protective role and preventing too much mortar from falling on the output pipeline, which is inconvenient to clean. The shielding rubber sheet 215 is fixed to the hopper by a clamping mechanism. The clamping mechanism includes a T-shaped slide rail 217 and a T-shaped groove pipe 218 that cooperates with the T-shaped slide rail 217. The upper end of the shielding rubber sheet 215 is elastically extruded into the gap between the T-shaped slide rail 217 and the T-shaped groove pipe 218. During use, place the shielding rubber sheet on the T-shaped slide rail, push the T-shaped groove pipe from one end of the T-shaped slide rail, and then lock the shielding rubber sheet. It is easy to install and disassemble and convenient and fast to clean.
