Description

Technical Field

[0001] The utility model belongs to the technical field of integrated wet spraying machine devices, and particularly relates to a hanging structure for the wet spraying machine device. Background Art

[0002] A wet spraying machine is a type of concrete spraying equipment primarily used for shotcrete construction in underground projects such as tunnels, culverts, subways, and foundation pit support. The wet spraying machine uses a hydraulic pump to deliver the concrete mix through a pipe to a nozzle. At the nozzle, the concrete mix is thoroughly mixed with high-pressure water mist and sprayed onto the work surface at a constant velocity. Traditional wet spraying machines use an air compressor to provide the hydraulic pumping pressure, requiring a separate location on site. The air compressor's associated air tanks and the compressor itself take up considerable space, and each unit must be individually wired. This increased number of wiring can create a cluttered site and increase electrical risks. When the wet spraying machine is moving within the foundation pit, if the length of the wiring exceeds the required length, the air compressor must be moved, resulting in inefficient construction. Furthermore, if the air compressor wiring is too long, it can easily bend, causing excessive resistance during operation and potentially causing pipe bursts.

[0003] In order to solve the above technical problems, the inventors designed an integrated wet spraying machine device, which integrated the equipment used for wet spraying operations and installed it on a walking mechanism. However, since the construction site is vast and is in the infrastructure construction stage, the integrated wet spraying machine device cannot be moved to some sites by itself. Sometimes it needs to be towed and transferred by a hooking rope through the central traveling head. The connection of the hooking rope requires manual binding, which is not only time-consuming and labor-intensive, but also has poor connection reliability. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a hanging structure for a wet spraying machine device.

[0005] The technical solution adopted by the utility model is a hanging structure for a wet spraying machine device, comprising a hanging joint and an isosceles tripod, the hanging joint being installed at one corner of the tripod, the other two corners of the tripod being hinged on two hinged ears, the two hinged ears being fixedly connected to the left side of the left wheel frame, and the left wheel frame being rotatably connected to the bottom of the mounting plate of the walking mechanism through a rotating mechanism.

[0006] Furthermore, the above-mentioned tripod includes a left top triangular plate frame and a hinged ear. Two pairs of side steel bars are welded to the two right corners of the left top triangular plate frame respectively. Each pair of side steel bars is arranged up and down at each corner of the left top triangular plate frame. A hinged ear is welded to the right end of each pair of side steel bars. Multiple transverse steel bars are welded between the two pairs of side steel bars to form an isosceles trapezoidal structure. The two ends of each transverse steel bar are located between each pair of side steel bars and are fixedly connected at the same time. Multiple vertical bars are welded on the outside between each pair of side steel bars.

[0007] Furthermore, the above-mentioned hanging joint includes a hanging tube and a lifting ear screw. The hanging tube is welded to the top of the connecting rod. The lifting ear screw is spirally connected to the connecting ear at the bottom of the connecting rod and locked with a nut. The connecting rod is fixedly connected to the left top corner of the left top triangle frame.

[0008] Compared with the existing technology, the beneficial effects of the present invention are that the frame structure adopts a hanging joint and an isosceles tripod, which is light in weight, convenient for hanging, has high rigidity and strength, and good hanging reliability. The isosceles trapezoidal structure transition connection frame composed of side steel bars, transverse steel bars and longitudinal steel bars can be welded with on-site scrap steel bars, which is convenient for welding and low in cost.

[0022] Example 2

[0023] See also Figure 1-5 and Figure 7-9The mortar that the wet spraying machine pushes out is pneumatically sprayed out through the air inlet end 4, and the mortar that the wet spraying machine pushes out is sprayed out through the air inlet end 4, and then is sprayed to the wall surface for bonding.

[0024] The left wheel frame 103 is connected to the left wheel frame 104 by a U-bolt, and the left wheel frame 103 is connected to the left wheel frame 104 by a U-bolt.

[0025] Among them, a grid net 202 is provided in the hopper 201 of the wet spraying machine 2, and the grid net 202 is connected to the step 204 provided in the hopper 201 through springs 203 at the four corners. A door frame 205 is provided on the grid net 202, and a pneumatic vibration pump 206 is fixedly connected to the door frame 205 and the height ensures that the pneumatic vibration pump 206 is higher than the top surface of the hopper 201. The mesh side wall cross-section of the grid net 202 is an isosceles triangle, and each grid hole formed by the mesh side wall has a trapezoidal cross-section in the vertical and horizontal directions; the use of the grid net on the hopper can break up the concrete fed into the mixing tank and evenly feed it into the mixing and feeding mechanism on the lower side, thereby improving the spraying quality of the concrete and facilitating the filtering of oversized particles to avoid entering the spraying mechanism and damaging the equipment. A door frame is provided in the hopper to suspend the pneumatic vibration pump above the hopper to avoid the moisture of the concrete in the hopper affecting the pneumatic vibration pump. A pneumatic vibration pump is used to prevent the electromagnetic vibration pump from being easily damaged in a humid environment. The conventional grille mesh adopts a square hole structure composed of round rod steel bars. Due to long-term use, concrete is easily generated on the grille mesh, which is difficult to clean and not easy to fall off under vibration. The present application adopts a mesh side wall with a blade structure, and in combination with vibration, it is very easy to achieve that the added concrete falls from the grille mesh to the mixing and feeding mechanism below, avoiding adhesion to the grille mesh after long-term operation and affecting the falling of concrete and difficulty in cleaning. Cleaning is more time-saving and labor-saving. Two handles are provided on the grille mesh to facilitate the disassembly of the grille mesh. A downward-inclined high-pressure jet port is provided around the spring 203, which can timely blow off the mortar generated on the spring to avoid affecting the vibration reduction performance of the spring. Under the condition of blowing and vibration, the mortar is less likely to stick to the spring and is easier to clean.

[0026] In order to protect the pneumatic vibration pump, a protective layer 207 is provided on the outside of the pneumatic vibration pump 206. The protective layer 207 is a barrel-shaped structure. After covering the pneumatic vibration pump 206, the bottom is fixedly connected to the door frame 205.

Two through holes 211 for installing the air inlet pipe and the air outlet pipe of the pneumatic vibration pump 206 are provided on the top of the protective layer 207. The two through holes 211 are embedded with a waterproof sleeve 212. The waterproof sleeve 212 is provided with an annular groove 213. The annular groove 213 is sealed and connected to the protective layer 207. The inner hole of the annular groove 213 is provided with multiple sealing rings 214. The use of a protective layer to cover the pneumatic vibration pump can effectively protect it from damage. The three-layer structure of waterproof, sponge and thermal insulation can provide waterproof, elastic protection and isolation from excessively high external temperatures. The provision of the waterproof sleeve facilitates the sealed insertion of the air inlet pipe and the air outlet pipe.

[0027] In order to protect the air pressure distribution valve 216, a shielding rubber 215 is fixed on the side wall of the hopper 201, and the shielding rubber 215 covers the air pressure distribution valve 216 fixed on the side wall of the hopper 201; the shielding rubber can prevent concrete from splashing and falling onto the air pressure distribution valve, causing the pressure distribution valve to be damaged for a long time due to solidified cement mortar. Pedals are provided on the bottom of the front and rear sides of the hopper 201. Standing on the pedals makes it convenient to perform feeding operations. A shielding rubber 215 is also provided on the bottom of the hopper facing the mixing tank, covering the bottom of the hopper 201. The output pipe plays a protective role to prevent excessive mortar from falling on the output pipe and making it inconvenient to clean. The shielding rubber 215 is fixed to the hopper with a clamping mechanism. The clamping mechanism includes a T-shaped slide rail 217 and a T-shaped slot tube 218 used in conjunction with the T-shaped slide rail 217. The upper end of the shielding rubber 215 is elastically squeezed into the gap between the T-shaped slide rail 217 and the T-shaped slot tube 218. When in use, the shielding rubber is placed on the T-shaped slide rail, and the T-shaped slot tube is pushed in from one end of the T-shaped slide rail to lock the shielding rubber. It is easy to assemble and disassemble, and cleaning is convenient and quick.

[0028] In order to facilitate the stable transportation of the entire equipment, a transportation fixing structure is installed on the walking mechanism 1, and the transportation fixing structure includes a U-shaped card 801 and a round tube 802. The U-shaped card 801 is fixedly connected to the bottom of the mounting plate 101 in an inverted manner, and the round tube 802 is rotatably connected to the U-shaped card 801.

Triangular clips 805 are set on both sides of the bottom of the walking wheel 102. The transportation fixing structure composed of the U-shaped clip, round tube, binding rope, hanging hole and triangular clip is set to firmly connect the walking mechanism to the transport cart to avoid shaking during transportation. The rotatable round tube can act as a pulley during the bundling process, facilitating the sliding of the binding rope and making the bundling tighter. After bundling, the anti-rotation mechanism is used to lock it, which can further improve the bundling stability. The anti-rotation device includes a ratchet 806 and a pawl 807. The ratchet 806 is fixedly connected to the left end of the circular tube 802. The pawl 807 used in conjunction with the ratchet 806 is rotatably connected to the U-shaped card 801 and the pawl 807 can overlap the ratchet teeth of the ratchet 806. It is loosened when used for bundling. The circular tube 802 is located in the U-shaped card 801 and a limiting plate 808 is provided on both sides on both sides to facilitate limiting and preventing slippage. The limiting plate 808 is fixedly connected to the circular tube 802 by welding. A through hole 809 is radially provided at the right end of the circular tube 802 to facilitate insertion of the steel pipe for rotation, and it is also convenient to wrap the binding rope around the circular tube and then insert it into the through hole for fixing. The circular tube is rotated to play the role of a winding drum, and cooperates with the anti-rotation device to realize the fixation of a binding rope between the corresponding hanging holes of the single-sided circular tube.
