Description

Technical Field

[0001] The utility model relates to the technical field of mine anchor stress sensor installation, in particular to a telescopic portable anchor stress sensor installation device. Background Art

[0002] As an effective means of mine pressure monitoring, anchor (cable) stress monitoring technology is now increasingly used in the field of coal mine engineering. With the help of anchor (cable) stress monitoring technology, mine personnel can timely grasp the force changes of anchors (cables) and understand the stress distribution of surrounding rocks in the mining space, so as to take engineering measures to prevent disasters in the first place. According to the on-site arrangement process of anchor (cable) stress measurement points, its installation content can be briefly described as two parts: ① Arrange anchors in the middle area of ​​the roof (middle of the production gang) (arrange anchor cables in the production gang area) - this engineering measure is generally completed in advance by the mine staff when doing support; ② Use perforated fixed installation, first put in the tray, insert the sensor into the anchor or anchor cable, keep the sensor centered, and finally tighten the anchor bolt's fastening nut - this engineering measure is installed on-site by the installer. It was found through on-site installation that during the installation of anchor rod (cable) stress gauges, there are some objective conditions that cause inconvenience in installation and even certain safety hazards. For example: ① The general tunnel height is set at 3-4m. At such a height, workers need to use a stepladder or other ladder-like auxiliary tools for installation. However, such auxiliary tools have their own balance instability when there is an inclination in the tunnel, which can easily cause the ladder to shake and slip; ② The anchor rod (cable) stress measurement points in the tunnel are generally designed in multiple places, and the process of transporting ladder-like auxiliary tools is inevitably time-consuming and laborious; ③ Belt conveyor equipment has been laid on one side of the production gang. When workers install it, they need to cross the belt conveyor equipment for installation. In this case, there are great safety hazards to the personal safety of workers.

[0003] To this end, in view of the main objective problems existing in the installation of the above three anchor (cable) measuring points, it is necessary to design an auxiliary installation tool that can meet the requirements of portability and safety. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0034] Figure 1-Figure 9This is a specific embodiment of the utility model, which is a telescopic portable anchor rod (cable) stress sensor installation device, which can be used for workers to safely and conveniently install anchor rod (cable) stress sensors, including a primary rod body telescopic device 1, a secondary rod body telescopic device 2, and a rod body manual rotation device 3.

[0035] The primary rod body telescopic device is composed of five parts, namely, a pointed rod 101, a nut fitting sleeve 102, a nut thin-plate baffle 103, a thin-plate baffle 106, a telescopic spring 104, a primary rod body 105 and a rod body fixing element 107. The pointed rod 101 is used in conjunction with the nut fitting sleeve 102; the pointed rod 101 is used to insert the nut 4, the stress sensor 5 and the tray 6, and the nut fitting sleeve 102 is used to embed the nut 4, and also provides a force in the process of delivering the nut 4, the stress sensor 5 and the tray 6 to the anchor rod (cable), so as to facilitate installation; the manufacturing process of the pointed rod 101: take a plastic rod, grind one end into a round tip, and grind the other end to have a thread, and tighten the threaded end into the nut baffle 1032 prepared in advance; the manufacturing process of the nut fitting sleeve 102: through the structural transformation of the stainless steel cylinder 1021, a groove 1022 for placing the nut is cut out in the middle of the cylinder, and then a through-hole 1023 is formed in the middle; the entire nut fitting sleeve 102 is finally welded to the primary rod body 105. The nut sheet baffle 103 is used to fix the pointed rod 101 and assist the first spring 104 to drive the pointed rod 101 to expand and contract along the rod body radial direction; the sheet baffle is a circular thin steel body 1031, wherein a nut baffle 1032 needs to be welded on the baffle near the side of the pointed rod, which is used for the pointed rod 101 to be rotated and inserted and fixed on the sheet baffle. The primary rod body 105 is a lightweight aluminum alloy cylindrical sleeve, which is used to insert the telescopic device composed of the pointed rod 101, the nut sheet baffle 103 and the first spring 104; the primary rod body 105 needs to be externally welded with a nut fitting sleeve 102 and a rod body fixing element 107. The rod fixing element 107 is achieved by welding a small telescopic device on the primary rod 105, and is composed of a hollow cylindrical structure 1074, a second spring 1073, a spring baffle 1072 and a cylindrical structure 1071. It has three functions: preventing the primary rod 105 from rotating horizontally about the center point of the cross section; achieving radial adjustment and telescoping of the primary rod 105 along the secondary rod 201, which is convenient for adjusting the length of the overall installation device to meet the on-site installation environment; and preventing the primary rod 105 and the secondary rod 201 from rotating asynchronously during the process of lifting the nut 4.

[0036] The secondary rod body telescopic device is composed of five parts, namely, the secondary rod body 201, the secondary rod body thin baffle plate 202, the third spring 203, the thin convex baffle plate 2042, the bearing 2043, and the hand grip 205. The secondary rod body 201 needs to be structurally modified, and a round hole 2011 is punched 5 cm below one end, and holes are punched again every 10 cm thereafter until 10 holes are punched, so as to facilitate the insertion of the fixing element of the primary rod body 105 and to adjust and assist the primary rod body 105 to telescope in the radial direction. The secondary rod body thin baffle plate 202, the third spring 203, and the thin convex baffle plate 2042 are combined into a set of secondary telescopic devices, which are used to assist the primary rod body 105 to telescope in the radial direction of the secondary rod body 201. The thin convex baffle 2042 is transformed from a cylinder, and the overall form is a three-layer cylindrical structure that is gradually reduced. The first layer of cylinder (with a diameter smaller than the inner ring of the bearing) is used to fit the inner ring of the bearing 2043 and weld it. The third layer of cylinder is the thin baffle. The second layer of cylinder is the same size as the inner ring structure of the bearing 2043 and is used to separate the first and second layers of cylinders. The thin convex baffle 2042, the bearing 2043, and the hand grip 205 form the rod body spin system structure 204. The hand grip 205 is a hollow cylinder, and the diameter of the outer center circle of its cross-sectional structure is the same as the outer ring of the bearing 2043, and the inner center circle diameter must be larger than the inner ring diameter of the bearing 2043; the hand grip 205 is welded to the bearing 2043.

[0037] The rod manual rotating device 3 is composed of a horizontal gear 301, a vertical gear 304, a rotating handle 305, and a device housing 306. The horizontal gear 301 is sleeved on the secondary rod 201, 2-3 cm above the bearing 2043, and welded; a vertical gear 304 is welded on the rotating handle 305, and penetrates the hand grip rod 305 with a pre-drilled hole 3041, and the vertical gear 304 is meshed with the horizontal gear 301, and finally a round rubber sleeve 303 is sleeved, and a second nut 302 is welded at a 1-2 mm gap; after the gear rotating system is installed, the rod is sleeved into a housing as a gear system protective shell.

[0038] The practical process of this embodiment is as follows:

[0039] Workers will put the tray, stress sensor and nut that need to be installed in the anchor rod (cable) on the pointed rod from top to bottom in sequence, and the nut needs to be embedded in the nut embedding sleeve; according to the required length, adjust the rod fixing element to adjust the length of the entire rod; align the pointed rod with the anchor rod (cable), push forward with force from the hand grip rod, and the pointed rod will retreat into the primary rod through the spring. At the same time, use the thrust of the nut embedding sleeve to deliver the tray, stress sensor and nut of the anchor rod (cable) to the anchor rod (cable); turn the rotating handle, use the gear system to drive the rod body self-spin system to make the rod body rotate, and finally tighten the nut on the anchor rod (cable) through the nut embedding sleeve to install the anchor rod (cable) stress sensor.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
