Description
Technical Field
[0001] The utility model relates to the technical field of drilling construction, in particular to an operating trolley for drilling holes on planes and high and steep slopes. Background Art
[0002] At present, in water conservancy projects, horizontal surface drilling generally adopts fixed brackets to set up fixed drilling work platforms, and the work platforms need to be installed and dismantled after drilling is completed; drilling on steep slopes is generally carried out in the following two ways: one is to set up scaffolding, and drill holes using the scaffolding platform by manual labor in conjunction with down-the-hole drills. This method requires large-scale scaffolding installation and dismantling, which is time-consuming, low in efficiency, and has high requirements for the stability of the scaffolding foundation, high requirements for civilized construction, and great safety hazards; the other is to use a high-arm anchor trolley. This method is expensive and has limited telescopic height, and it also requires reasonable planning of temporary roads and work platforms.
[0003] Taking into comprehensive consideration factors such as convenient operation, wide application range, safe use, low requirements for the use environment, fast and efficient, a working trolley for drilling holes on flat surfaces and steep slopes has been specially developed. Utility Model Content
[0004] The purpose of the utility model is to provide a drilling trolley for plane and steep slope drilling to solve the problems encountered in the above-mentioned background technology.
[0005] To achieve the above purpose, the technical solution of the utility model is as follows:
[0006] A work trolley for drilling holes on flat surfaces and steep slopes comprises a moving mechanism, a support frame and a drilling device. The drilling device is fixedly mounted on the support frame, and the support frame is movably mounted on one side of the top of the moving mechanism. Winches connected to steel ropes are mounted on both sides of the moving mechanism, and wheels are provided at the four ends of the moving mechanism.
[0007] In one embodiment, a driving device is provided on the top of the moving mechanism, a base of the driving device is hingedly connected to the moving mechanism, and a working end of the driving device is hingedly connected to the bottom of the support frame. The driving device can be a pneumatic cylinder or a hydraulic cylinder for raising or lowering the support frame.
[0008] In another embodiment, a blocking rod is fixed to the top of the moving mechanism on a side away from the support frame, the support frame is rotatably connected to the moving mechanism, and limiting mechanisms for limiting the support frame are evenly provided on the blocking rod.
[0009] Preferably, the limiting mechanism includes a base, a spring, and a positioning plate. The baffle rod is provided with an installation groove, the base is installed in the installation groove of the baffle rod, the positioning plate is connected to the base through a spring, and the top of the positioning plate is provided with a card slot that matches the rod body of the support frame.
[0010] In the above solution, the support frame is made of welded steel pipes, and the steel wire rope connected to the winch passes through the gap of the support frame in the vertical direction.
[0011] In the above scheme, the drilling device includes a body, a support plate, a base, a chassis, and a slide. The working end of the body is provided with a drill bit mounting sleeve, the body is installed on the top of the base, the two sides of the base are connected to the chassis by screws, the bottom of the base is installed with a slide, the bottom of the slide is fixedly connected to the support frame through the support plate, the two sides of the base are slidably connected to the two sides of the slide through pulleys, and the front and rear of the pulleys are provided with traction chains that drive the body to move forward and backward.
[0012] As a preferred solution, a limiting plate is further provided at the rear of the pulley, and the center hole of the limiting plate is coaxially arranged with the center hole of the drill mounting sleeve; the support plate is a triangular structure.
[0013] Compared with the existing technology, the beneficial effects of the present invention are as follows: when working on a slope, the trolley is first hoisted to the working position by a winch control, and then the conveying angle of the drilling device is determined by adjusting the angle of the support frame, so that it can adapt to the construction work of drilling holes on flat surfaces and steep slopes. Compared with the traditional method of setting up a fixed drilling work platform for horizontal drilling, this trolley does not need to be installed or disassembled, and can be moved to the next drilling point at any time. This trolley saves the time for installing and disassembling the scaffolding and does not require processing the basic frame of the work platform. Compared with the slope drilling method using a high-arm anchoring trolley, the overall project cost of this trolley is only 6,000 to 10,000 yuan, which greatly reduces the construction cost, and can cover the entire slope drilling operation from the dam top to the dam foundation, without the need to build a horse trail or work platform in the middle.

DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention will now be further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the relevant components of the present invention.
[0021] According to the technical solution of the present invention, without changing the essential spirit of the present invention, those skilled in the art may propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are merely illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.
[0022] The technical solution of the present utility model is further described in detail below with reference to the accompanying drawings and embodiments.
[0023] Example 1, as Figure 1 and Figure 2 As shown, a working trolley for drilling holes on flat surfaces and steep slopes includes a moving mechanism 1, a support frame 3 and a drilling device 4. The support frame 3 is raised so that the trolley is about 1.8m long, about 1.7m wide and about 1.5m high. Four wheels 12 are set at the bottom of the trolley as the moving mechanism 1 to facilitate the trolley to move on slopes and horizontal surfaces.
[0024] The drilling device 4 can adopt the drilling equipment in the prior art, such as a down-the-hole drill, and the drilling device 4 is fixedly mounted on the support frame 3. The support frame 3 is movably mounted on one side of the top of the mobile mechanism 1, so as to facilitate the adjustment of its conveying angle to the drilling device 4, and facilitate drilling on flat surfaces and steep slopes. The mobile mechanism 1 includes a chassis frame body, which can be made of welded steel pipes. Winches 11 connected to steel wire ropes are installed on both sides of the mobile mechanism 1, and two winches 11 are installed on both sides of the chassis frame body for lifting the trolley to the work area. Wheels 12 are provided at the four ends of the mobile mechanism 1, and the wheels 12 have locking components and need to be locked manually. A servo motor that drives the wheels 12 to rotate is also installed on the chassis frame body. The four workshops can be connected in a linkage manner, which is the same as the current conventional electric four-wheel vehicle transmission method.
[0025] When working on a slope, two small winches 11 are installed at the bottom of the trolley. The model of winch 11 can be selected based on the difficulty of the on-site operation and the type of down-the-hole drill. First, the trolley is hoisted into position using the winch 11. The end of the wire rope must be tied to a tree or a solid structure at the top of the slope. The operator, also at the top of the slope, fastens his safety belt and follows the trolley into position. He adjusts the down-the-hole drill to the hole location, turns on the down-the-hole drill operation switch, and begins drilling on the slope. Once drilling is completed, the trolley is moved to the next work area.
[0026] In order to better connect the support frame 3 to the top of the mobile mechanism 1, a driving device (not shown in the figure) is provided on the top of the mobile mechanism 1. The base of the driving device is hinged to the mobile mechanism 1, and the working end of the driving device is hinged to the bottom of the support frame 3. The driving device can be a pneumatic cylinder or an oil cylinder. By installing an articulated seat on the top of the mobile mechanism 1 and the bottom of the support frame 3, and then connecting the bottom of the pneumatic cylinder or oil cylinder to the top articulated seat of the mobile mechanism 1, and hingedly connecting the end of the telescopic rod of the pneumatic cylinder or oil cylinder to the bottom articulated seat of the support frame 3, similar to the current truck unloading device, it can be adjusted to different angles within an adjustable range of 0-45 degrees, meeting the drilling operation requirements of the trolley on flat surfaces and steep slopes.
[0027] Example 2, please refer to Figure 1 and Figure 4 , different from Example 1, a baffle 2 is fixed on the side of the top of the mobile mechanism 1 away from the support frame 3. There are two baffles 2, which are installed on both sides of the mobile mechanism 1. The support frame 3 is rotatably connected to the mobile mechanism 1, and the baffles 2 are evenly provided with limiting mechanisms for limiting the support frame 3. The support frame 3 is assembled with φ50×4 seamless steel pipes. After assembly, the plane of the mobile mechanism 1, the baffle 2, and the support frame 3 adopt a triangular structure when viewed from the side to enhance the stability of the trolley. The conveying angle of the support frame 3 to the drilling device 4 is adjusted according to the angle of the anchor rod entering the rock, so that it can adapt to the construction operation of drilling holes on planes and steep slopes. During plane operations, the surface of the down-the-hole drill rig is vertical, and the steel pipes of the support frame 3 are connected by high-strength clips.
[0028] Specifically, the limiting mechanism includes a base 21, a spring 22, and a positioning plate 23. During implementation, the retaining rod 2 is provided with a mounting slot, and the base 21 is installed within the retaining rod 2, with the slot facing inward. The positioning plate 23 is connected to the base 21 via the spring 22. Positioning components are also installed at each end of the spring 22 to fix the position of the spring 22. The top of the positioning plate 23 is provided with a slot 24 that mates with the rod body of the support frame 3. The steel pipes on both sides of the support frame 3 can be placed in the slot 24.
[0029] Because the limiting mechanisms are evenly arranged on the blocking rods 2, the limiting mechanisms on each side of the two blocking rods 2 are symmetrically arranged. Compared with the solution of Example 1, the support frame 3 in Example 1 can automatically adjust the working direction of the drilling device 4 under the drive of the driving device, while in this embodiment, the working direction of the drilling device 4 needs to be adjusted manually. When lowering the drilling angle of the down-the-hole drill, just press the positioning plate 23 to make it elastically sink into the installation groove, so that the rod body of the support frame 3 enters the slot 24 of the next limiting mechanism. When raising the drilling angle of the down-the-hole drill, lift the rod bodies of the support frames 3 on both sides. With the help of the external inclined surface of the positioning plate 23, the positioning plate 23 can be elastically sunk into the installation groove under the action of the spring 22. At this time, the rod body of the support frame 3 can pass over the previous limiting mechanism and be lifted to a certain angle.
[0030] In practice, support frame 3 is constructed from welded steel pipes, such as φ50×4 seamless steel pipes. The wire rope connected to hoist 11 passes vertically through the gaps in support frame 3, facilitating wire rope hoisting of the trolley. A rotating shaft can also be mounted on positioning plate 23, with both ends secured to lever 2. When pressed, the shaft contracts within the mounting groove, centered around the shaft, and is reset by spring 22.
[0031] Example 3, based on Examples 1 and 2, please refer to Figure 3 The drilling device 4 can also be configured as follows: it includes a body, a support plate 42, a base 43, a chassis 44, and a slide 47. The body is the body of the down-the-hole drill. The working end of the body is equipped with a drill bit mounting sleeve 48 for mounting a suitable alloy drill bit for drilling. The body is mounted on top of the base 43. The two sides of the base 43 are connected to the chassis 44 by screws. The bottom of the base 43 is mounted with a slide 47. The bottom of the slide 47 is fixedly connected to the support frame 3 via the support plate 42. The two sides of the base 43 are slidably connected to the two sides of the slide 47 via pulleys 45. The front and rear ends of the pulleys 45 are equipped with traction chains 41 that drive the body forward and backward.
[0032] The traction chain 41 is driven by another servo motor and pulls the machine body to move in a straight line along the direction of the slide 47 to facilitate the insertion of the drill bit. The pulley 45 at the bottom is installed between the base 43 and the chassis 44 and plays a guiding role by sliding with the outer side of the slide 47.
[0033] Furthermore, as a preferred solution, a limit plate 46 is provided at the rear of the pulley 45. The center hole of the limit plate 46 is coaxial with the center hole of the drill bit mounting sleeve 48. The limit plate 46 is used to collect cables and define the initial position of the down-the-hole drill body. In this solution, the support plate 42 is a triangular structure to enhance the stability of the drilling device 4. The sleeve rod 31 can be first secured to the support frame 3, and then the bottom sides of the support plate 42 are secured to the sleeve rod 31, providing stable support for the drilling device 4.
[0034] In summary, compared to the traditional method of horizontal drilling using a fixed drilling platform, this trolley does not require installation or removal and can be moved to the next drilling location at any time. This saves scaffolding installation and removal time and eliminates the need to modify the platform foundation. Compared to slope drilling using a high-arm anchor trolley, the overall project cost of this trolley is only 6,000 to 10,000 yuan, significantly reducing construction costs. It can also cover the entire slope from the dam crest to the dam base, eliminating the need for intermediate horse paths or work platforms.
[0035] In addition to the above advantages, the high and steep slope spray anchor support has a wide range of applications and a high safety factor when using this drilling operation trolley. It can be applied to slopes above 30° where manual standing drilling is not possible.
[0036] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
