Description

Technical Field

[0001] The invention belongs to the technical field of drilling equipment, and in particular relates to a wheel frame type slope drilling equipment. Background Art

[0002] Slope construction projects involve drilling operations. Holes are drilled on the slope and explosives are placed in the holes. The slope surface is blasted to remove floating rocks and expose the solid inner rock. At the same time, protective works such as metal protective nets are applied to the slope surface to significantly improve the safety of the slope. Especially for roadside slopes, protective construction will help improve the safety of the highway environment and avoid vehicle accidents caused by falling rocks.

[0003] The equipment used to drill holes in the slope usually uses a drilling rig, and the continuously rotating drill rod cuts the rock to form a hole. However, the following problems exist in actual construction: due to the complex surface structure and low flatness of the slope, it is not easy to set the drilling rig at the hole position and keep it stably at the hole position during the drilling operation cycle. The solution in the prior art is to build a supporting scaffolding on the slope as a construction platform. However, the method of building a temporary construction platform leads to a significant reduction in construction efficiency, and the drilling holes on the slope surface are usually designed to be multiple. After completing the drilling at the current position, the construction platform needs to be adjusted, such as increasing the height, before setting the next hole, and the drilling rig needs to be moved, which further affects the construction efficiency. On the other hand, due to the problems of falling rocks on the slope itself, there are great safety hazards in the existing method of building a construction platform and manually operating the drilling rig on the construction platform to drill holes.

[0004] In summary, it is necessary to develop and design a new type of slope drilling equipment to solve the above-mentioned technical problems. Summary of the invention

[0017] The present invention provides a wheel-frame slope drilling device. Compared with the existing method of building a construction platform in front of the slope and manually operating the drilling device on the construction platform to drill holes, the drilling device in the present invention is constructed based on a wheel-frame trolley with self-propelled ability. During construction, the wheel-frame trolley is against the slope surface and shifted along the slope surface. The lifting and lowering displacement of the drilling device along the slope surface is achieved by retracting and releasing the hanging cable through a winch. The left and right displacement of the drilling device along the slope surface is achieved by operating the stabilizing cable. After being in place, the position of the drilling device on the slope surface is anchored by fixing the lower end of the stabilizing cable. Therefore, the wheel-frame slope drilling device of the present invention can carry out slope drilling construction without building a construction platform such as a scaffolding in front of the slope, thereby solving the problem of low construction efficiency caused by building and adjusting the construction platform. At the same time, after the current slope surface road is completed, it can be moved to the next hole position very quickly and conveniently, which significantly improves the construction efficiency of slope drilling construction.

[0018] On the other hand, the power supply device, water supply device and controller of the wheel frame slope drilling equipment are all arranged on the ground in front of the slope. The ground operator controls the drilling equipment to perform various actions through the controller, so that potential injury accidents caused by falling rocks on the slope surface during construction can be avoided by staying away from the slope. The rear wheels of the wheel frame trolley in the present invention are pushed and pulled by the electric push rod, so when the drilling equipment is against the slope surface and the drilling device and the drill rod are aligned with the drilling point on the slope surface, the angle between the drill rod and the slope surface can be adjusted to a certain extent through the action of the electric push rod.

[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0024] See also Figure 1 and Figure 2 The wheel frame type slope drilling equipment of the present invention is constructed based on a wheel frame type trolley. The wheel frame type trolley includes a chassis 19 with a bracket 17 installed, a front wheel 20 and a travel motor 16 driving the front wheel 20 are installed at the front of the chassis 19, and electric push rods 3 are installed on both sides of the rear part of the chassis 19, and rear wheels 4 are installed at the ends of the telescopic rods of the electric push rods 3.

[0025] The front wheels 20 and the travel motor 16 are used to drive the slope drilling equipment to move on the ground, and the rear wheels 4 and the electric push rod 3 are used to control the wheel frame trolley to tilt to a certain angle during drilling construction to control the drilling angle, such as Figure 1 As shown in the figure, the rear wheel 4 and the front wheel 20 fall on the slope surface. When the piston rod of the electric push rod 3 is extended, the drilling equipment will rotate clockwise at a certain angle. On the contrary, when the piston rod of the electric push rod 3 is retracted, the drilling equipment will rotate counterclockwise at a certain angle.

[0026] In this embodiment, the bracket 17 includes a front frame, a rear frame, a top frame and a middle frame, wherein the bottom edge of the front frame is fixedly connected to the front edge of the chassis 19, the bottom edge of the rear frame is fixedly connected to the rear edge of the chassis 19, the front edge of the top frame is fixedly connected to the top edge of the front frame, and the rear edge is fixedly connected to the top edge of the rear frame, the top edge of the middle frame is fixedly connected to the middle of the top frame, and the bottom edge is fixedly connected to the middle of the chassis 19.

[0027] Furthermore, in the present embodiment, the length dimension of the top frame of the bracket 17 is significantly smaller than the length dimension of the chassis 19, and the width dimension of the top frame of the bracket 17 is equal to the width dimension of the chassis 19, so that the wheeled trolley is a conical document structure with a small top and a large bottom, and the angle between the top front frame and the rear frame of the bracket 17 and the chassis 19 is 45 to 60°. In the structure shown in the figure, the angle between the top front frame and the rear frame of the bracket 17 and the chassis 19 is 60°.

[0028] A drilling device is installed in the middle of the front part of the bracket 17, and winches 13 for retracting and releasing the hanging cables 22 are installed on both sides of the front part of the bracket 17. A stabilizing cable 5 is connected to the rear part of the bracket 17. The stabilizing cable 5 is provided with two left and right cables, and the upper end is fixedly connected to the rear part of the top frame of the bracket 17. The two winches 13 and their hanging cables 22 are used to suspend the main part of the equipment during drilling construction, and the main part of the equipment is suspended and maintained at a certain height position on the slope surface. By controlling the two winches 13 to synchronously retract and release the two hanging cables 22, the height of the main part of the equipment on the slope surface can be adjusted. The stabilizing cable 5 has two functions: one is to anchor the drilling equipment. When the main part of the drilling equipment reaches the drilling point and the drilling angle is adjusted, the lower ends of the two stabilizing cables 5 are fixed to anchors on the ground, such as ground anchors, so that the main body of the equipment can be anchored on the slope surface, which can improve the stability of the drilling process; the other function is that when the main body of the equipment needs to be shifted horizontally to the left and right on the slope surface to move to the next drilling point, the construction personnel on the ground can pull the two stabilizing cables 5 to make the main part of the drilling equipment leave the slope surface appropriately, and then pull it to the left or right to shift it.
