Description

Technical Field

[0001] The utility model relates to the field of anchoring support, and particularly relates to an efficient sawing auxiliary device for a hollow anchor rod body, which is used to improve the sawing efficiency of the hollow anchor rod body. Background Art

[0002] With the wide application of the bolt support technology in fields such as coal mines, tunnels and mines, the demand for metal bolts is relatively large. According to the actual requirements of construction projects, the bolt body needs to be sawed into different lengths. Most of the sawing machines used for sawing the bolt body use top and side hydraulic devices to limit the object to be sawed. Since there are corrugated threads on the surface of the bolt body, when sawing in a conventional bundled manner, there are gaps between the bolt bodies and they cannot be pressed tightly. During sawing, the bolt bodies will rotate, resulting in tooth breakage and unable to perform bundled sawing. The efficiency of sawing a single row of bolt bodies is very low. Therefore, in view of the problem that the bolt bodies cannot be pressed tightly when directly bundled and the bundled sawing of the bolt bodies cannot be completed, the utility model designs a tooling to assist in bundling and sawing the bolt bodies, so that the bolt bodies can be pressed tightly against each other without rotating, and high-efficiency sawing of the bolt bodies can be achieved. Content of the Utility Model

[0003] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides an efficient sawing auxiliary device for a hollow anchor rod body.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an efficient sawing auxiliary device for a hollow anchor rod body, which includes a bundling device and a clamping tooling. The bundling device includes eight connecting blocks, among which: the first connecting block and the second connecting block, the third connecting block and the fourth connecting block, the fifth connecting block and the sixth connecting block, the seventh connecting block and the eighth connecting block are respectively connected by welding; the second connecting block, the fourth connecting block, the sixth connecting block are respectively connected to the seventh connecting block, the fifth connecting block, the eighth connecting block; the opening angles of the left and right clamping blocks of the clamping tooling are equal to the included angle between the first connecting block and the seventh connecting block.

[0005] Further, the included angles between the first connecting block and the second connecting block, the third connecting block and the fourth connecting block, the fifth connecting block and the sixth connecting block, the seventh connecting block and the eighth connecting block that are welded together are all 120 degrees.

[0006] Further, the included angles between the first connecting block and the seventh connecting block, the seventh connecting block and the eighth connecting block, the third connecting block and the fifth connecting block, the fifth connecting block and the eighth connecting block are all 120 degrees.

[0007] Further, U-shaped grooves are arranged on the seventh connecting block, the fifth connecting block and the eighth connecting block, and the positions where the second connecting block, the fourth connecting block and the sixth connecting block are fixed on the seventh connecting block, the fifth connecting block and the eighth connecting block can be adjusted through the U-shaped grooves.

[0008] Further, the second connecting block, the fourth connecting block, and the sixth connecting block are respectively connected to the seventh connecting block, the fifth connecting block, and the eighth connecting block by bolts.

[0009] Further, two threaded holes are machined on each of the second connecting block, the fourth connecting block, and the sixth connecting block.

[0010] Further, the opening angles of the left and right clamping blocks of the clamping tooling are both 120 degrees.

[0011] Further, the upper opening height h1 of the clamping tooling is less than the lower opening height h2.

[0012] Further, the clamping tooling is connected to the side hydraulic device of the sawing machine.

[0013] Compared with the prior art, the positive effects of the present utility model are as follows:

[0014] By designing a hexagonal bundling auxiliary device, the present utility model bundles the anchor rod bodies into a regular hexagonal structure; then, by designing a wedge-shaped pressing tooling and cooperating with the hydraulic device of the sawing machine to pre-tighten the side surfaces of the bundled anchor rod bodies, and then starting the sawing machine for sawing, the efficient sawing of the bundled anchor rod bodies can be completed. The specific advantages are as follows:

[0015] 1. The bundling device is designed as an adjustable structure, and the number of bundled anchor rod bodies is expandable: each side of this device is designed as an adjustable structure. During use, according to the specific number of anchor rod bodies to be bundled, each side of the bundling device can be adjusted to the corresponding length. This bundling device is suitable for bundling different numbers of anchor rod bodies.

[0016] 2. The processing technology of the tooling is simple and the cost is low: the bundling device and the clamping tooling can be processed by cutting, drilling, tapping threaded holes, milling U-shaped holes, welding, etc. Each process is simple to process and has high efficiency. Therefore, it has good processability and low production cost.

[0017] 3. The bundling method is simple and the efficiency is high: the anchor rod bodies to be bundled are sequentially placed into the bundling device, and then a common steel belt strapping machine is used to pre-tighten the rod bodies, and the bundling can be completed.

[0018] 4. The bundling and clamping of the anchor rod bodies are firm and the stability is good: by using the bundling device, the anchor rod bodies are bundled into a regular hexagonal structure, and then the clamping tooling is used in cooperation with the hydraulic device of the sawing machine for clamping, and effective pre-tightening is formed between adjacent rod bodies. During sawing, the rod bodies will not rotate.

[0019] 5. High efficiency of bundled sawing of anchor rod bodies: The anchor rod bodies are bundled into a regular hexagon structure and sawed in a bundled manner. A large number of anchor rod bodies can be sawed at one time, effectively reducing the auxiliary time for handling, adjusting the sawing position, and clamping the anchor rod bodies, improving the sawing efficiency and reducing the sawing cost.

Detailed Embodiment

[0029] The structure of the bundling device of the present utility model is as shown in Figure 1 and Figure 2As shown, an adjustable structure design is adopted, including components such as connecting blocks and bolts. The connecting blocks are connected by welding, and U-shaped holes are machined inside to form an adjustable regular hexagon frame, and the size of the regular hexagon frame can be adjusted according to the number of anchor rod bodies to be bundled. Bolts and nuts are used to fix the regular hexagon frame to form a stable bundling structure. The specific details are as follows. The device is composed of the first connecting block 1, the second connecting block 2, the third connecting block 3, the fourth connecting block 4, the fifth connecting block 5, the sixth connecting block 6, the seventh connecting block 7, and the eighth connecting block 8. Among them, the first connecting block 1 and the second connecting block 2, the third connecting block 3 and the fourth connecting block 4, the fifth connecting block 5 and the sixth connecting block 6, the seventh connecting block 7 and the eighth connecting block 8 are respectively connected by welding, and the included angle between the two welded connecting blocks is 120 degrees. Two threaded holes are machined on each of the second connecting block 2, the fourth connecting block 4, and the sixth connecting block 6, and U-shaped grooves are machined in the middle of the fifth connecting block 5, the seventh connecting block 7, and the eighth connecting block 8. The second connecting block 2 and the seventh connecting block 7, the fourth connecting block 4 and the fifth connecting block 5, the sixth connecting block 6 and the eighth connecting block 8 are connected by bolts and can move positions in the U-shaped grooves. After adjusting to the appropriate positions, bolts 9 and nuts 10 can be used for pre-tightening to complete the assembly of the bundling device. After the assembly is completed, the included angles between the first connecting block 1 and the seventh connecting block 7, the seventh connecting block 7 and the eighth connecting block 8, the third connecting block 3 and the fifth connecting block 5, the fifth connecting block 5 and the eighth connecting block 8 are all 120 degrees.

[0030] Figure 3 It is a diagram showing the bundling of anchor rod bodies using a bundling device. First, adjust each connecting block to the appropriate position and pre-tighten it with bolts and nuts. Then, sequentially place the anchor rod bodies into the bundling device, and use a steel belt strapping machine to shrink the steel belt 11 to pre-tighten the rod bodies, and the bundling operation of the rod bodies can be completed.

[0031] Figure 4It is a diagram showing the sawing of bundled anchor rod bodies. First, place the anchor rod bodies into the bundling device and adjust the device size to arrange the anchor rods in a regular hexagon. Then, use steel straps to pre-tighten the bundled anchor rod bodies to form a firm bundling structure. Next, transfer the bundled anchor rod bodies to the sawing machine, and use the clamping tooling in cooperation with the hydraulic device of the sawing machine to pre-tighten the anchor rods from the side and the top. Finally, start the sawing machine for sawing to achieve efficient and stable sawing of the anchor rod bodies. The specific details are as follows: Transfer the bundled anchor rods to the sliding roller path of the sawing machine, install the clamping tooling 12 on the sides of the bundled anchor rods respectively. The clamping tooling is designed with a 120° opening structure and can fit well with the sides of the bundled anchor rods. Starting the side hydraulic device 13 of the sawing machine can effectively pre-tighten the sides of the bundled anchor rods. Design the clamping tooling into an asymmetric structure with a lower upper opening height, that is, the upper opening height h1 is less than the lower opening height h2, and the height difference is not greater than half of the outer diameter of the anchor rod body to be sawed, so as to ensure that the top hydraulic device 14 of the sawing machine can directly apply a load to the topmost anchor rod without applying the load on the clamping tooling 12. Through the above method, the degrees of freedom of the bundled anchor rods in four directions can be effectively restricted, and the rod body at the bundling center position is also firmly pressed. Finally, start the sawing program of the sawing machine, and the saw blade 15 starts to saw the anchor rods.

[0032] The bundling method and sawing method using the auxiliary device of the present utility model:

[0033] 1) Bundling method

[0034] a) Assembly of the bundling device: Determine the number of required bundling devices according to the length of the anchor rods. Adjust the sides of the bundling device to the corresponding lengths and pre-tighten them with bolts and nuts.

[0035] b) Place the anchor rod bodies: Place a certain number of anchor rod bodies into the bundling device in sequence so that the rod bodies placed in the bundling device form a regular hexagon.

[0036] c) Pre-tighten with steel straps: Wind the steel strap around the anchor rods for one week, and then use a steel strap bundling machine to shrink the steel strap to bundle the anchor rod bodies so that the bundled anchor rod bodies still maintain the shape of a regular hexagon after being separated from the bundling device.

[0037] 2) Sawing method

[0038] a) Hoisting of the anchor rods: Use a crane to hoist the bundled anchor rod bodies onto the roller path of the sawing machine and adjust the position of the bundled anchor rod bodies.

[0039] b) Install the clamping tooling: Install the clamping tooling on the sides of the bundled anchor rod bodies.

[0040] c) Hydraulic clamping: Start the hydraulic pressing program of the sawing machine to fasten the sides and the top of the bundled anchor rod bodies.

[0041] d) Start sawing: Start the sawing program of the sawing machine to saw the bundled anchor rod bodies.

[0042] The working principle of this utility model:

[0043] When using the traditional bundling method, the anchor rods are arranged freely without constraints and have irregular shapes. Directly bundling with steel belts 11 cannot constrain all the rods on the edge, resulting in gaps between the rods, which cannot be effectively compressed. Figure 5 In addition, if a clamping fixture of a single shape is designed, it cannot adapt to all irregularly shaped bundled rods. The pressure applied by the hydraulic device on the side and top of the sawing machine cannot completely constrain the rod. When sawing, the rod will be rotated and teeth will be broken, and the rod sawing operation cannot be completed.

[0044] The innovation of the utility model is that the anchor rod bodies are first placed in the bundling device, and the anchor rod bodies are closely contacted with each other through the structural restrictions of the bundling device to form a regular hexagonal arrangement, such as Figure 6 In this way, the steel belt can effectively compress the rods on each side, and evenly transfer the pressure brought by the steel belt to the inner rods, so that all the rods are firmly tied, as shown in Fig. Figure 6 At the same time, since the bundled anchor rods are arranged in a regular hexagon, the designed clamping fixture combined with the hydraulic device can apply uniform pressure to each side, such as Figure 6 As shown in c), the stability of the bundled anchor rod bodies is further enhanced to ensure that the anchor rod bodies will not rotate during the sawing process.
