Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, and in particular to a grain temperature rod insertion and removal tooling structure. Background Technology

[0002] Grain temperature rods, also known as grain storage temperature measuring rods, are used to monitor grain temperature during storage to ensure the quality and safety of stored grain. To monitor the grain temperature in various parts of the grain pile in real time, several grain temperature lines (each with approximately 3-5 temperature sensors) need to be installed in the grain pile. To ensure the integrity of the sensors during use, the grain temperature rods are usually inserted into the grain pile and the grain temperature lines are installed in the grain temperature rods after the grain is stored. When the grain is removed, the temperature lines are taken out and the grain temperature rods are pulled out. Because the temperature rods are cylindrical and relatively smooth with few stress points, inserting them into the grain pile and pulling them out are both very difficult. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a grain temperature rod insertion and removal tooling structure that is simple in structure and easy and labor-saving to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A grain temperature rod insertion and removal fixture structure includes a bracket and clamping arms rotatably disposed at both ends of the bracket. The clamping arms are symmetrically distributed, and the inner end of each clamping arm is provided with a clamping block. The opposing sides of the two clamping blocks are provided with clamping surfaces. When the grain temperature rod is positioned between the two clamping surfaces, and the outer end of the clamping arm is pulled to bring the two clamping surfaces closer together and clamp the grain temperature rod, the clamping blocks drive the grain temperature rod to move synchronously. Simultaneously, when the clamping arm is pulled in the opposite direction to move the two clamping surfaces away from each other and release the grain temperature rod, the clamping blocks separate from the grain temperature rod.

[0006] By adopting the above technical solution: when inserting the grain temperature rod, the grain temperature rod is passed through the space between the two clamping surfaces. When the outer end of the clamping arm is pressed down, the two clamping blocks clamp the grain temperature rod, thereby using the clamping arm to help insert the grain temperature rod into the grain pile. After inserting a section of the grain temperature rod, the fixture is loosened and moved upward a certain distance, then the grain temperature rod is clamped again and pressed down. This reciprocating motion inserts the entire grain temperature rod into the grain pile. When it is necessary to remove the grain temperature rod, the fixture is reversed, and the upper end of the grain temperature rod is passed through the two clamping blocks. When the outer end of the clamping arm is pulled upward, the clamping blocks clamp the grain temperature rod, thereby pulling the grain temperature rod out of the grain pile a certain distance. The clamping blocks are then loosened, the fixture is moved downward a certain distance, and the grain temperature rod is clamped again and pulled out. With the help of this fixture, the grain temperature rod can be quickly and conveniently inserted or removed.

[0007] Preferably, the bracket includes two parallel connecting plates and pins at both ends of the connecting plates. The middle part of the clamping arm is provided with a shaft hole, and the pin passes through the shaft hole to form a rotatable connection.

[0008] Preferably, the connecting plate has connecting holes at both ends, and the pin is configured as a Torx bolt. The Torx bolt passes through the connecting hole and the shaft hole and is then fastened by a Torx nut. The Torx bolt and Torx nut connection makes installation and disassembly very convenient.

[0009] Preferably, the connecting plate has outwardly bent reinforcing ribs at both its upper and lower edges. These reinforcing ribs increase the strength of the connecting plate, allowing it to better withstand the forces exerted on the clamping arm.

[0010] Preferably, two sets of limiting members are provided between the connecting plates, forming a limiting gap between the two sets of limiting members for the grain heating rod to pass through. The limiting members increase the connection strength between the connecting plates and also limit the grain heating rod to a certain extent.

[0011] Preferably, the limiting component is configured as a limiting bolt, which passes through one connecting plate and is threadedly connected to another connecting plate. This makes installation and disassembly of the limiting bolt and the connecting plate more convenient.

[0012] Preferably, the clamping arm includes a gripping section and a clamping section, with an obtuse angle between the gripping section and the clamping section. When the clamping surface clamps the grain temperature rod, the clamping section and the axis of the grain temperature rod form an angle α, which is configured to be 30°≤α≤60°. The obtuse angle between the gripping section and the clamping section allows for a clear view of the tooling's orientation during use. When the clamping block clamps the grain temperature rod, the angle α between the clamping section and the grain temperature rod enables better self-locking between the clamping surface and the surface of the grain temperature rod.

[0013] Preferably, the clamping surface is configured as an arc-shaped frosted surface. The arc-shaped frosted surface increases the friction between the clamping surface and the surface of the grain temperature rod.

[0014] Preferably, the clamping arm and clamping block are configured as a single unit, and are forged from 45# steel. This single-unit forging results in high overall strength and greater structural stability.

[0015] Therefore, this utility model has the advantages of simple structure and convenient and labor-saving use. Attached Figure Description

[0024] To make the technical problem to be solved, the technical solution, and the beneficial technical effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model.

[0025] It should be understood that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the number of technical features indicated. Features specified as "first" or "second" may expressly or implicitly indicate that at least one of those features is included.

[0026] like Figures 1-6 The illustrated grain temperature rod insertion and removal fixture structure includes a support 1 and clamping arms 2 rotatably disposed at both ends of the support 1. The clamping arms 2 are symmetrically distributed, and the inner end of each clamping arm 2 is provided with a clamping block 3. The opposing sides of the two clamping blocks 3 are provided with clamping surfaces 30. When the grain temperature rod 4 is positioned between the two clamping surfaces 30, and the outer end of the clamping arm 2 is pulled to bring the two clamping surfaces 30 closer together and clamp the grain temperature rod, the clamping blocks 3 drive the grain temperature rod 4 to move synchronously. At the same time, when the clamping arm 2 is pulled in the opposite direction to move the two clamping surfaces 30 away from each other and release the grain temperature rod 4, the clamping blocks 3 separate from the grain temperature rod 4.

[0027] The support 1 includes two parallel connecting plates 10 and pins 11 at both ends of the connecting plates 10. The clamping arm 2 has a shaft hole 200 in the middle, through which the pins 11 pass to form a rotatable connection. The connecting plates 10 have connecting holes 100 at both ends, and the pins 11 are configured as star bolts 110. The star bolts 110 pass through the connecting holes 100 and the shaft holes 200 and are then fastened with star nuts 111. The upper and lower edges of the connecting plates 10 are provided with outwardly bent reinforcing ribs 101. Two sets of limiting members 12 are provided between the connecting plates 10, forming a limiting gap 13 for the grain temperature rod to pass through. The limiting members 12 are configured as limiting bolts 120, which pass through one connecting plate 10 and are threadedly connected to the other connecting plate 10.

[0028] In some embodiments, such as Figure 2 As shown, the clamping arm 2 includes a gripping section 20 and a clamping section 21. The gripping section 20 and the clamping section 21 form an obtuse angle. When the clamping surface 30 clamps the grain temperature rod, the clamping section 21 and the axis of the grain temperature rod form an angle α. The angle α is configured to be 30°≤α≤60°. The clamping surface 30 is configured as an arc-shaped frosted surface. In this embodiment, the angle α is configured to be 50°.

[0029] In some embodiments, the clamping arm 2 and the clamping block 3 are configured as an integral structure, and the clamping arm 2 and the clamping block 3 are integrally forged from 45# steel.

[0030] Referring to the accompanying drawings, the principle of this utility model is as follows: Figure 7 As shown, pull the grain temperature rod 4 out of the grain pile, and then use the tooling according to... Figure 7 Install the tool onto the grain temperature rod in the direction shown. Hold the outer end of the clamping arm and pull it upwards. The two clamping blocks will then move closer together and clamp the grain temperature rod through the clamping surfaces. The greater the pulling force F, the tighter the clamping blocks will clamp until the clamping surfaces self-lock with the grain temperature rod. At this point, the grain temperature rod will move upwards with the tool (pulling it out of the grain pile). Then release the clamping arms and move the tool downwards along the grain temperature rod a short distance. Repeat the above actions until the grain temperature rod is completely pulled out of the grain pile. Figure 8 As shown, insert the grain temperature rod into the grain pile, and follow the tooling instructions. Figure 8 The direction shown connects to the grain temperature rod, applying a downward pressure F to the outer end of the clamping arm, causing the clamping block to clamp the grain temperature rod and insert it into the grain pile. This type of tooling has a simple overall structure and high strength, and can stably clamp the grain temperature rod, providing assistance for inserting or removing the grain temperature rod, thus making it easier to insert or remove the grain temperature rod from the grain pile with less effort.

[0031] In the description of this utility model, it should be understood that the directions or positional relationships indicated by up, down, left, right, inner end, outer end, one end, and the other end are based on the orientation or positional relationships shown in the accompanying drawings. They are only for the purpose of more clearly describing the technical solution of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as a limitation of this utility model.

[0032] Although specific embodiments of the present invention are described in detail herein, they are given for illustrative purposes only and should not be construed as limiting the scope of the present invention. Various substitutions, alterations, and modifications may be conceived without departing from the spirit and scope of the present invention.
