Description

Technical Field

[0001] This utility model relates to a slope drilling and grouting construction trolley. Background Technology

[0002] In water conservancy and hydropower, mining, highway and railway construction projects, slope reinforcement and protection are crucial for ensuring construction safety. Common slope reinforcement methods include anchor bolt support, grouting reinforcement, and shotcreting with wire mesh. These processes typically require drilling and grouting operations on the slope surface. However, due to the large slope gradient (usually 30°~70°) and complex geological conditions (such as loose soil layers and fractured rock masses), traditional construction methods have the following problems:

[0003] 1. Limitations of traditional construction platforms

[0004] (1) Scaffolding erection method:

[0005] Steel pipe scaffolding needs to be erected on the slope, which consumes a lot of manpower and materials, and the stability is greatly affected by the geology of the slope.

[0006] The scaffolding cannot be moved flexibly, and it needs to be dismantled and re-erected after each section of construction is completed, which is inefficient.

[0007] On steep or loose slopes, scaffolding is prone to slippage or even collapse, posing a significant safety hazard.

[0008] (2) Simple suspended platform or cable-stayed platform:

[0009] The suspended platform is suspended by steel wire ropes, and workers work directly on the platform, but it has poor stability and is greatly affected by wind.

[0010] The inability to adjust the platform angle makes drilling, grouting, and other operations difficult, affecting the quality of construction.

[0011] Based on the above problems, we designed a slope drilling and grouting construction trolley that can be displaced along the slope and has high stability. Utility Model Content

[0012] The technical problem to be solved by this utility model is to provide a slope drilling and grouting construction trolley that can be displaced along the slope and has high stability.

[0013] To solve the above problems, the present invention adopts the following technical solution:

[0014] A slope drilling and grouting construction trolley includes,

[0015] A sled structure that slides along a slope under the traction of a winch.

[0016] Platform device, one end of which is rotatably engaged with the sled structure;

[0017] An electric push rod is rotatably mounted between the sled structure and the platform device.

[0018] The controller controls the electric actuator.

[0019] Preferably, the sled structure includes two parallel sled rods, with a connecting rod fixed between the two sled rods. Both ends of the sled rods are closed, and a traction ring is rotatably installed at one end of each sled rod. The traction ring works in conjunction with the steel cable of a winch. A first rotating seat is provided at the top of the sled rod near the traction ring, and a second rotating seat is provided at the center of the top of the sled rod. The platform device rotates along the first rotating seat, and the electric push rod rotates along the second rotating seat.

[0020] Preferably, the bottom of the sled is provided with a blade, the lower end of which is machined into a cutting edge. The thickness of the cutting edge tapers downwards in an arc shape, and the two ends of the blade are arc-shaped transitions. When dragged on a slope, the blade cuts into the soil layer, thus restricting the lateral displacement of the sled.

[0021] Preferably, the platform device includes two parallel platform rods, a first connecting rod fixed between the two platform rods, a rotating plate fixed at the left end of each platform rod, a pin connecting the rotating plate and the first rotating seat, a third rotating seat located slightly to the right of the midpoint of each platform rod, and the upper end of the electric push rod rotatably connected to the third rotating seat; two or more supports are provided at the top of each platform rod, and a platform is mounted between two platform rods via the supports.

[0022] Preferably, the platform includes a platform plate, a column welded to the top edge of the platform plate, and a guardrail welded to the upper end of the column. A door is rotatably installed on the column. A protective net is installed on the outside of the column. The platform plate is fixed to the support.

[0023] Preferably, an arc-shaped bone plate is fixed between the two platform rods, and the middle part of the bone plate arcs upward and supports the bottom of the platform plate.

[0024] Preferably, a kickboard is installed at the top edge of the platform plate.

[0025] The beneficial effects of this utility model are:

[0026] Adaptive slope anchoring: The blade structure at the bottom of the sled adopts an arc-shaped blade design, which can be embedded in the soil layer by 30~50mm, effectively suppressing lateral slippage (measured displacement <2mm / m), avoiding the trolley from tipping over during construction, and improving the stability when towing the trolley.

[0027] Double protection design: The platform device is equipped with guardrails, safety nets and kickboards to prevent tools from falling and people from falling, and is especially suitable for high-altitude and steep slope operations.

[0028] Rapid movement: Using dual winches for synchronous traction (error ≤ 5%), the sled structure can slide along the slope at a speed of up to 0.5m / min, which is more than 4 times more efficient than traditional scaffolding; thus meeting the needs of continuous drilling and grouting operations.

[0029] Wide slope range: Adjustable via electric push rod, it can adapt to slopes greater than 30° (traditional tracked equipment is limited to <30°), making it especially suitable for steep slopes in water conservancy projects. Attached Figure Description

[0042] See Figure 1 The slope drilling and grouting construction trolley shown includes,

[0043] The sled structure 1 slides along the slope under the traction of a winch.

[0044] Platform device 2, one end of which is rotatably engaged with sled structure 1;

[0045] An electric push rod 3 is rotatably mounted between the sled structure 1 and the platform device 2.

[0046] The controller controls the electric push rod 3.

[0047] When implementing the above technical solution, a winch is installed at the top of the slope in advance. Each construction trolley needs to be equipped with two winches that operate synchronously. The steel cable of the winch is connected to the climbing sled structure 1. By winding the winch, the device is pulled up along the slope, and the drilling and grouting construction of the slope is completed during the pulling process.

[0048] The electric push rod 3 can adjust the relative angle of the platform device 2, so that when the sled structure 1 is in contact with the slope, the platform device 2 can be kept horizontal, making it convenient for workers to work on it.

[0049] See Figure 2and Figure 3 As shown, the sled structure 1 includes two parallel sled rods 11, with a connecting rod 12 fixed between them. The sled rods 11 and the connecting rod 12 are fixed by welding. The diameter of the sled rod 11 is 89mm, and the diameter of the connecting rod 12 is 45mm. Both ends of the sled rod 11 are closed in a spherical manner. The sled rod 11 is a hollow rod with a wall thickness greater than 16mm. In this embodiment, the wall thickness of the sled rod 11 is 20mm. A traction ring 13 is rotatably installed at one end of the sled rod 11. The traction ring 13 is used in conjunction with the steel cable of the winch. The traction ring 13 is made of Φ20 round steel. A first rotating seat 14 is provided at the top of the plow rod 11 near the position of the traction ring 13. A second rotating seat 15 is provided at the center position of the top of the plow rod 11. Both the first rotating seat 14 and the second rotating seat 15 are fixed to the plow rod 11 by welding. Ribs can be added as needed. The platform device 2 rotates along the first rotating seat 14, and the electric push rod 3 rotates along the second rotating seat 15.

[0050] The sled pole 11 is made of Φ89×20mm seamless steel pipe with spherical closed ends (radius 45mm) and can be filled with counterweight material to enhance stability.

[0051] The traction ring 13 is made of Φ20 round steel bent into a U shape and is rotatably connected to the sled rod 11.

[0052] See Figure 2 and Figure 4 As shown, the bottom of the sled 11 is provided with a blade 111. The blade 111 is made of the same material as the sled 11 and is connected by welding. The blade 111 is 12mm thick. The lower end of the blade 111 is machined to form a cutting edge 112. The thickness of the cutting edge 112 tapers downward in an arc. The two ends of the blade 111 are arc-shaped transitions. When dragged on the slope, the blade 111 cuts into the soil layer, thus restricting the lateral displacement of the sled 11.

[0053] In the above technical solution, when the steel cable is dragging the sled pole 11, the blade 111 will slide into the slope, making the sled pole 11 more stable when moving up and down along the slope.

[0054] The embedding depth of the blade 111 is 30~50mm.

[0055] See Figure 2 , Figure 5 and Figure 6As shown, the platform device 2 includes two parallel platform rods 21, with a first connecting rod 22 fixed between them. The platform rods 21 and the first connecting rod 22 are welded together. To reduce the load on the electric push rod 3, the diameter of the platform rod 21 is smaller than the diameter of the sled rod 11. In this embodiment, the diameter of the platform rod 21 is 60mm and the wall thickness is 16mm. A rotating plate 23 is fixed to the left end of the platform rod 21. The rotating plate 23 is welded to the platform rod 21. Specifically, a groove is first cut at the end face of the platform rod 21, then the rotating plate 23 is inserted into the groove and welded. This method of fixing results in a stronger connection between the rotating plate 23 and the platform rod 21. A pin is fitted between the rotating plate 23 and the first rotating seat 14 for rotational support. The diameter of the pin is selected according to the load-bearing requirements. In this embodiment, the diameter of the pin is 22mm. A third rotating seat 24 is provided at a position slightly to the right of the midpoint of the platform rod 21. The position of the third rotating seat 24 is located slightly to the right of the center of the platform rod 21, which makes the platform rod 21 more stable under load. The upper end of the electric push rod 3 is rotatably connected to the third rotating seat 24. The electric push rod 3 is fitted with pins between the second rotating seat and the third rotating seat 24 respectively. Two or more supports 25 are provided on the top of each platform rod 21. In this embodiment, there are two supports 25 on a single platform rod 21. A platform 26 is installed between two platform rods 21 through the supports 25.

[0056] In the above technical solution, the angle between the platform rod 21 and the sled rod 11 is adjusted by the cooperation of the rotating plate 23 and the first rotating seat, and by the cooperation of the electric push rod with the second and third rotating seats respectively. This is to meet the construction needs of this device on slopes with different gradients.

[0057] See Figure 5 As shown, the platform 26 includes a platform plate 261, a column 262 welded to the top edge of the platform plate 261, and a guardrail 263 welded to the upper end of the column 262. A door 264 is rotatably installed on the column 262. A protective net 265 is installed on the outside of the column 262. The platform plate 261 is fixed to the support 25.

[0058] In the above technical solution, a combination of columns 262, guardrails 263 and protective netting 265 is used to form lateral protection on the upper part of the platform 261, so as to prevent workers from falling off the platform during construction.

[0059] See Figure 5 As shown, an arc-shaped bone plate 27 is fixed between the two platform rods 21. The middle part of the bone plate 27 arcs upward and supports the bottom of the platform plate 261.

[0060] The design of the bone plate 27 is to increase the structural strength of the middle position of the platform plate 261 and increase the load-bearing capacity of the platform plate 261.

[0061] The 27-piece bone plate is made of spring steel and is 6mm thick.

[0062] See Figure 6 As shown, a kick plate 266 is installed at the top edge of the platform plate 261.

[0063] The purpose of the kickboard 266 is to prevent items placed on the platform 261 from falling.

[0064] The reason is that the protective net 265 has mesh, and commonly used tools such as screws and nails can easily fall out through the mesh.

[0065] Installing the 266 baseboard can effectively avoid this problem.

[0066] Construction process:

[0067] Two 5T winches are installed at the top of the slope, with a synchronization error of ≤5%;

[0068] Pull the trolley to the foot of the slope and start the electric push rod 3 to level the platform;

[0069] Segmented drilling and grouting, with the trolley lifted once every 3m segment.

[0070] Parameter verification:

[0071] In the 45° slope test, the lateral displacement of the blade 111 is <2mm / m;

[0072] When the platform bears a load of 500kg, the deformation of the 27-piece skeleton plate is ≤3mm.
