[0002] The front frame of a mining wet concrete spraying machine is the core load-bearing structure of the entire machine, and it needs to adapt to the narrow spaces, high load vibrations, and complex terrain underground. In existing technologies, the front frame of wet concrete spraying machines is mostly a welded one-piece structure with a high degree of component integration. This not only requires complete disassembly for maintenance and replacement, but also results in low efficiency in underground operations. In addition, due to the large amount of steel used and the heavy weight of existing front frames, the overall mobility of the machine is poor and the energy consumption is high. Utility Model Content
[0003] To address the shortcomings of the existing technology, this utility model provides a front frame for a wet concrete spraying machine and a wet concrete spraying machine, which can effectively solve the problems of poor maneuverability and high maintenance costs of existing wet concrete spraying machines during underground construction.
[0004] To achieve the above objectives, this utility model provides a front frame for a wet concrete spraying machine, including a frame body and mudguard components rigidly connected to both sides of the frame body. The mudguard components include a support groove and an arched mudguard plate.
[0005] The support groove is fixedly connected to the outer wall of the mudguard, and a quick-setting agent box is provided on the support groove, with the side of the quick-setting agent box overlapping the mudguard.
[0006] In one embodiment, the quick-setting agent tank is attached to the corresponding mudguard assembly by an elastic band.
[0007] In one embodiment, support leg assemblies are rigidly connected to both sides of the frame body;
[0008] The support groove is fixedly connected to the outer wall of the first end of the mudguard, and the leg assembly is adjacent to the second end of the mudguard.
[0009] In one embodiment, the frame body includes two opposing side plates;
[0010] A hinge seat is fixedly connected between the first ends of the two side plates;
[0011] A boom support is fixedly connected between the second ends of the two side plates.
[0012] In one embodiment, a swing bridge support is fixed between the two side plates to support and limit the swing bridge.
[0013] In one embodiment, a support assembly is provided between the two side plates and at a position corresponding to the position between the swing bridge support and the hinge seat;
[0014] The top of the support assembly has a power compartment module assembly station and a hydraulic module assembly station, with the hydraulic module assembly station located between the power compartment module assembly station and the hinge seat.
[0015] The bottom of the support assembly has a diesel tank module assembly station.
[0016] In one embodiment, the support assembly is further provided with a battery mounting base on top, and the battery mounting base is provided with a boom support base on top.
[0017] In one embodiment, a cover is installed on the two side panels, the cover covering the power compartment module assembly station;
[0018] The top and / or sides of the cover have access panels.
[0019] In one embodiment, the support groove and the mudguard are both bolted to the outer wall of the corresponding side plate.
[0020] In one embodiment, a limit rod is detachably connected to the hinge seat or the side plate.
[0021] Compared with the prior art, the present invention has the following beneficial technical effects:
[0022] 1. This utility model integrates support grooves on the mudguard assemblies on both sides of the front frame, so that accelerator tanks can be installed on both sides of the mudguard assemblies. This allows for the storage of accelerators using two separate accelerator tanks. Under the premise of keeping the accelerator storage capacity unchanged or even increasing, the volume of a single accelerator tank can be effectively reduced, and the filling height of the accelerator can be reduced. At the same time, the accelerator tanks are installed next to the mudguards, which does not occupy the space outside the mudguards, effectively reducing the overall width of the front frame, so that the front frame can meet the working requirements of narrow cross sections.
[0023] 2. In the preferred embodiment of this utility model, the accelerator box is fixed to the mudguard assembly by means of an elastic band, so that the elastic band can be used to absorb the vibration during the operation of the concrete wet spraying machine, thereby enhancing the stability of the accelerator box during operation.
[0024] 3. In the preferred embodiment of this utility model, by reserving a power compartment module assembly station and a hydraulic module assembly station on the top of the support component, and placing the hydraulic module assembly station between the power compartment module assembly station and the hinge seat, the hydraulic module can be installed in the remaining space between the two side plates after the power compartment module is assembled on the two side plates. This enhances the space utilization between the two side plates without occupying the space on the outside of the two side plates, so that there is enough space on the outside of the two side plates to install the quick-setting agent tank.
[0025] 4. In the preferred embodiment of this utility model, the side plate, the hinge seat, and the boom support are used to form the frame body. The side plate, the hinge seat, and the boom support can all be single-plate structures and welded and fixed, thereby reducing unnecessary mounting brackets and realizing the lightweight design of the front frame.

[0039] like Figure 1 , Figure 2The diagram shows a concrete wet spraying machine front frame (hereinafter referred to as "front frame") disclosed in this embodiment, which mainly includes a frame body 1 and mudguard assemblies 2 rigidly connected to both sides of the frame body 1. The mudguard assembly 2 includes a support groove 201 and a mudguard plate 202 with an arched folded plate structure. The support groove 201 is connected to the outer wall of the mudguard plate 202 by welding or bolting. A quick-setting agent tank 3 is provided on the support groove 201. The side of the quick-setting agent tank 3 has a folded structure adapted to the outer wall of the mudguard plate 202, so that the side of the quick-setting agent tank 3 can directly overlap the mudguard plate 202. That is, the quick-setting agent tank 3 is supported by the support groove 201 and the mudguard plate 202 at the same time, so that the quick-setting agent tank 3 has high assembly stability.
[0040] In this embodiment, by integrating support grooves 201 on the mudguard assemblies 2 on both sides of the front frame, the quick-setting agent tanks 3 can be installed on both sides of the mudguard assemblies 2. This allows for the use of two separate quick-setting agent tanks 3 to store the quick-setting agent. Under the premise of keeping the storage amount of quick-setting agent unchanged or even increasing, the volume of a single quick-setting agent tank 3 can be effectively reduced, and the filling height of the quick-setting agent can be reduced. At the same time, by installing the quick-setting agent tanks 3 next to the mudguard 202, the space outside the mudguard 202 is not occupied, which effectively reduces the overall width of the front frame, enabling the front frame to meet the working requirements of narrow cross sections.
[0041] In a preferred embodiment, the quick-setting agent tank 3 is secured to the corresponding mudguard assembly 2 using an elastic band. Specifically, both ends of the elastic band have buckles or fixing bolts. One end of the elastic band is buckled or bolted to the top of the mudguard 202, and the other end is buckled or bolted to the bottom of the support groove 201 after passing over the top and side of the quick-setting agent tank 3. By fixing the quick-setting agent tank 3 to the mudguard assembly 2 using the elastic band, the vibration during the operation of the wet concrete spraying machine can be absorbed, further enhancing the stability of the quick-setting agent tank 3 during operation.
[0042] In the specific implementation process, outrigger assemblies 4 are rigidly connected to both sides of the frame body 1. The support groove 201 is fixedly connected to the outer wall of the first end of the mudguard 202, and the outrigger assembly 4 is adjacent to the second end of the mudguard 202. Preferably, the support groove 201, mudguard 202, and outrigger assembly 4 are all connected and fixed to the frame body 1 by high-strength bolts treated with Dacromet. The high-strength bolts treated with Dacromet facilitate disassembly and maintenance and are more suitable for harsh working environments.
[0043] refer to Figure 3The frame body 1 includes two opposing side plates 101. A hinge seat 102 is fixedly connected between the first ends of the two side plates 101 for hinged connection of the rear frame. A boom support 103 is fixedly connected between the second ends of the two side plates 101 for mounting the boom. In practice, the side plates 101, hinge seat 102, and boom support 103 can all be single-plate structures and welded together, thereby reducing unnecessary mounting brackets and achieving a lightweight design for the front frame.
[0044] In practical applications, the hinge seat 102 has a connecting ear plate, which is hinged to the rear frame via a pin. Simultaneously, a steering cylinder 5 is also hinged to the hinge seat 102, and the steering cylinder 5 is also hinged to the rear frame. The steering angle between the front and rear frames can be controlled by extending and retracting the steering cylinder 5. Preferably, a limit rod 6 is detachably connected to the hinge seat 102 or the side plate 101. One end of the limit rod 6 can be sleeved on a pre-reserved pin welded to the hinge seat 102 or the side plate 101, and the other end can also be sleeved on a pre-reserved pin on the rear frame. When the concrete wet spraying machine is running or under maintenance, the limit rod 6 is fixed to the corresponding pin, limiting the hinge between the front and rear frames and preventing sudden steering injuries.
[0045] In the specific implementation process, a swing bridge support 7 is fixed between the two side plates 101 to support and limit the swing bridge. Specifically, the swing bridge support 7 has a shaft hole, and the shaft hole is located on the central axis of the front frame. The drive shaft 8 of the swing bridge is clearance-fitted with the shaft hole, so that the swing bridge always stays near the central axis of the vehicle during the swing process, maintaining the stability of the vehicle.
[0046] In the specific implementation process, a support assembly 9 is provided between the two side plates 101 and at the position corresponding to the swing bridge support 7 and the hinge seat 102. The support assembly 9 includes several steel structure support members bolted or welded between the two side plates 101 or on the inner wall of the two side plates 101. The top of the support assembly 9 has a power compartment module assembly station and a hydraulic module assembly station, with the hydraulic module assembly station located between the power compartment module assembly station and the hinge seat 102. The bottom of the support assembly 9 has a diesel tank module assembly station. (Reference) Figure 4The power compartment module 10 is mounted on the top of the chassis body 1, while the diesel tank module 11 is horizontally and flatly mounted on the diesel tank module assembly station, i.e., the bottom of the chassis body 1. This reduces the diesel tank installation space, saves diesel tank mounting bracket material, reduces the vehicle body size, and simultaneously reduces the weight of the front chassis. Furthermore, after the power compartment module 10 is mounted on the two side panels 101, a hydraulic module can be installed in the remaining space between the two side panels 101 (i.e., the hydraulic module assembly station). This enhances the space utilization between the two side panels 101 without occupying the space on the outer sides of the two side panels 101, ensuring sufficient space on the outer sides of the two side panels 101 for installing the quick-setting agent tank 3.
[0047] In the specific implementation process, a battery mounting bracket 12 is also provided on the top of the support component 9, and the battery mounting bracket 12 does not interfere with the power compartment module 10. A boom support bracket 13 is provided on the top of the battery mounting bracket 12. Compared with the previous structural design in which the battery mounting bracket and boom support bracket are fixed on the front frame respectively, this embodiment installs the boom support bracket 13 on the top of the battery mounting bracket 12. This not only eliminates the need for the mounting bracket of the boom support bracket 13 on the front frame, making the frame body 1 lighter and smaller, but also provides a larger visual space for the operator in the cab and makes it easier to operate.
[0048] In the specific implementation process, a cover 14 is also bolted to the two side plates 101. The cover 14 covers the power compartment module assembly station, that is... Figure 5 As shown. Meanwhile, the top and / or side of the cover 14 have maintenance covers, which are connected to the cover 14 by hinges or bolts. During maintenance, the corresponding maintenance covers can be flipped open or removed, effectively solving the problem of inconvenient maintenance of the power compartment module 10.
[0049] The above description is only a preferred embodiment of the present utility model and does not limit the scope of protection of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
