Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe fixing, in particular to a propulsion beam oil pipe limiting device. Background Art

[0002] At present, rock drilling trolleys are widely used in mining. The rock drill is the core working mechanism. It reciprocates on the propulsion beam when working. The hydraulic oil pipe connected to the rock drill reciprocates together with the rock drill, bypassing the oil pipe tensioning turntable guide, and one end is fixed on the oil pipe bracket on the side of the propulsion beam to form a pulley action. The oil pipe must be tightened and fixed.

[0003] The hydraulic oil pipe of the rock drill is fixed on the oil pipe bracket of the propulsion beam by a splint. As the rock drill reciprocates, the hydraulic oil pipe of the rock drill is easy to loosen and then fall out of the groove of the oil pipe tensioning turntable, causing the oil pipe to be squeezed. The out-of-groove oil pipe is also easy to scrape against the working mechanisms such as the propulsion beam and drill arm, causing wear and rupture of the hydraulic oil pipe.

[0004] The traditional rock drill oil pipe fixing bracket on the trolley propulsion beam is fixed with a single or multiple hydraulic oil pipes and rubber hoses in the notch of the bracket by bolting the clamping plate. Each time the oil pipe is replaced, one or several people need to hold the oil pipe, and another person needs to tighten the bolts to install the clamping plate. The installation is difficult, and the tightness of the clamping plate is difficult to control. If the oil pipe is pressed loose, it will not be fixed tightly. If it is pressed too tightly, it will cause the oil pipe to be blocked, which will affect the normal operation of the rock drill. As the rock drill reciprocates, the oil pipe is pulled, the hydraulic oil pipe is easy to loosen, and the outer skin of the part where the rubber hose is pressed and fixed will be damaged, which will cause damage to the hydraulic oil pipe. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and propose a propulsion beam oil pipe limiting device. The oil pipe clamped by the utility model is not easy to loosen during movement, and will not cause oil pipe blockage, and reduce the damage of the traditional clamping plate to the rubber hose part of the hydraulic oil pipe, which can greatly reduce the loss of the hydraulic oil pipe of the rock drilling trolley, reduce the cost of use, and reduce the maintenance workload.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A thrust beam oil pipe limiting device comprises a bearing assembly and an oil pipe joint installed on the surface of the bearing assembly, the bearing assembly comprises a bearing base plate and a limiting plate installed on the upper end of the bearing base plate, a limiting channel is formed in the middle position of the limiting plate, a vertically arranged positioning plate is detachably connected to the limiting channel, a positioning opening is formed on the surface of the positioning plate for the oil pipe joint to pass through, a protective cover is detachably fixed to the positioning plate and the upper end of the limiting plate, and the oil pipe joint is fixed to the positioning plate by a bolt assembly.

[0008] Preferably, the positioning plate partially penetrates the bearing bottom plate and extends to the lower end of the bearing bottom plate, and positioning openings are formed on both sides of the positioning plate.

[0012] Preferably, the bolt assembly includes a first nut and a second nut threadedly connected to the oil pipe joint, and the first nut and the second nut fix the oil pipe joint and the positioning plate from both sides.

[0013] Preferably, the limiting plate is fitted with the positioning plate, and the two are perpendicular to each other.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] This device optimizes the way of fixing the oil pipe.

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0023] Please refer to the attached Figure 4 The traditional rock drill oil pipe fixing bracket on the trolley propulsion beam is fixed with a single or multiple hydraulic oil pipes and rubber hoses in the notch of the bracket by bolting the clamping plate. Each time the oil pipe is replaced, one or several people must hold the oil pipe, and another person tightens the bolts to install the clamping plate. The installation is difficult, and the tightness of the clamping plate is difficult to control. If the oil pipe is pressed loose, it will not be fixed tightly. If it is pressed too tightly, it will cause the oil pipe to be blocked, which will affect the normal operation of the rock drill. As the rock drill reciprocates, the oil pipe is pulled, the hydraulic oil pipe is easy to loosen, and the outer skin of the part where the rubber hose is pressed and fixed will be damaged, which will cause damage to the hydraulic oil pipe.

[0024] In order to solve the above-mentioned problem of oil pipe fixing, refer to the attached Figure 1 -Attached Figure 3A propulsion beam oil pipe limiting device includes a bearing assembly 200 and an oil pipe joint 300 installed on the surface of the bearing assembly 200. The oil pipe joint 300 is a steel structure that can be stably installed on the surface of the bearing assembly 200. Oil pipes are connected to both ends of the oil pipe joint 300 to ensure stable transportation of oil.

[0025] Specifically, the bearing assembly 200 includes a bearing base plate 220 and a limiting plate 240 installed on the upper end of the bearing base plate 220. A limiting channel 241 is formed in the middle position of the limiting plate 240. A vertically arranged positioning plate 500 is detachably connected to the limiting channel 241. A positioning opening 510 for the oil supply pipe joint 300 to pass through is opened on the surface of the positioning plate 500. The oil pipe is fixed by the combination of the positioning plate 500 and the oil pipe joint 300 instead of the traditional bolt-fastening clamp 100, and there is no need to worry about the oil pipe loosening. At the same time, the oil pipe is fitted and fixed stably, and the oil pipe will not be damaged during the movement.

[0026] A protective cover 600 is detachably fixed to the upper ends of the positioning plate 500 and the limit plate 240. The protective cover 600 can protect the limit plate 240 and the positioning plate 500 from the outside and can also limit and fix the positioning plate 500. The oil pipe joint 300 is fixed to the positioning plate 500 by the bolt assembly 400. The oil pipe joint 300 can be stably fixed in the positioning opening 510 by the bolt assembly 400, thereby ensuring the stability of the oil pipe joint 300 and the oil pipes on both sides.

[0027] Please refer to the attached Figure 2 ; The positioning plate 500 here partially penetrates the bearing base plate 220 and extends to the lower end of the bearing base plate 220. Specifically, a positioning groove 221 is opened on the surface of the bearing base plate 220 and passes through the upper and lower parts. The positioning groove 221 can allow the positioning plate 500 to pass through. The positioning plate 500 is provided with positioning openings 510 on both sides of the bearing base plate 220. Different types of oil pipes can be fixed on both sides of the positioning plate 500, which meets the needs of pumping oil by the oil pipe and optimizes the route of the oil pipe installation.

[0028] A baffle 230 is fixed to the first side wall of the bearing base plate 220, and a mounting seat 210 is fixed to the second side wall. A plurality of mounting holes 211 are opened on the surface of the mounting seat 210. The baffle 230 can strengthen the strength of the overall structure from the outside. One side of the mounting seat 210 is connected to the propulsion beam through the mounting hole 211 to realize the installation of the overall structure.

[0029] The limit plate 240 here is fitted with the positioning plate 500 and the two are perpendicular to each other. The limit channel 241 is located in the middle position of the limit plate 240, and can limit the positioning plate 500 from both sides to ensure the stability of the installation of the positioning plate 500; at the same time, the limit plate 240 and the positioning plate 500 are perpendicular to each other to form a cross reinforcement structure, which further ensures the stability of the overall structure and the limitation of the oil pipe joint 300.

[0030] In order to further ensure the stability of the positioning of the positioning plate 500, a step surface is opened on the first side wall of the positioning plate 500 to match the baffle 230, and a limit block 520 is fixed on the second side wall to match the supporting bottom plate 220. The size of the limit block 520 is larger than the size of the bottom positioning groove 221. During the installation process, one end of the limit block 520 is slid and inserted toward the positioning groove 221, and the bottom can be vertically limited by the limit block 520. At the same time, the two sides of the limit block 520 can be limited by the limit plate 240 and the baffle 230, thereby ensuring the stability of the bottom; in the middle position, the step surface of the side wall of the positioning plate 500 can fit with the baffle 230, thereby further ensuring the stability of the positioning plate 500 from the middle position.

[0031] Specifically, the protective cover 600 includes a first protective plate 620 and a second protective plate 610 perpendicular to the first protective plate 620. A first locking hole 621 is opened on the surface of the first protective plate 620, and a second locking hole 242 corresponding to the first locking hole 621 is opened on the upper end of the limiting plate 240. The L-shaped protective cover 600 is fixed from the upper end, and the first locking hole 621 and the second locking hole 242 can be fixed by bolts, which can protect the oil pipe joint 300 in the middle position, and at the same time, the positioning plate 500 can be limited from the upper end to achieve the limited fixation of the positioning plate 500.

[0032] Specifically, the bolt assembly 400 includes a first nut 410 and a second nut 420 which are threadedly connected to the oil pipe joint 300. The first nut 410 and the second nut 420 fix the oil pipe joint 300 and the positioning plate 500 from both sides. After the oil pipe joint 300 is fixed, the oil pipe joint 300 can be stably clamped on the surface of the positioning plate 500 by rotating the first nut 410 and the second nut 420 from both sides respectively, thereby ensuring the stability of the limit of the oil pipe joint 300. At the same time, the whole is easy to disassemble and assemble, and can be quickly disassembled and replaced.

[0033] When the utility model is used, the positioning plate 500 is first inserted into the limiting channel 241, and then the oil pipe joint 300 is passed through the positioning opening 510 on the surface of the positioning plate 500, and the oil pipe joint 300 is fixed from both sides by the bolt assembly 400; then the protective cover 600 and the limiting plate 240 are fixed from the top position to limit the positioning plate 500.

[0034] One side of the mounting seat 210 of the oil pipe limiting device is fixed to the surface of the propulsion beam, and the oil pipe is connected with both ends of the oil pipe joint 300 to ensure the connection of the oil.

[0035] This device optimizes the method of fixing the oil pipe. The oil pipe on the surface of the propulsion beam is installed and limited by setting a combination of the oil pipe joint 300 and the positioning plate 500. The overall structure will not affect the transportation of oil in the oil pipe, and the overall structure is stable and can move stably with the propulsion beam to ensure stable transportation of oil.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
