Description

Technical Field

[0001] This utility model belongs to the field of steel processing technology, specifically relating to a straightening device for probe steel rods. Background Technology

[0002] A steel chisel is a common construction tool, especially in road construction in mountainous areas. It is usually driven into soft rock by a sledgehammer to drill holes, and explosives are then loaded into the holes to blast the rocks. It is also commonly used to pry rocks, explore the soil layers below the bottom of the foundation pit to determine the soil's hardness, and to detect the presence of pits, ancient tombs, ancient wells, air-raid shelters, and other underground structures.

[0003] When inspecting the operation of a two-stage gasifier in a steel plant, a probe hole needs to be opened and a steel rod inserted. During coal combustion, incomplete combustion or improper furnace condition adjustments can easily lead to slag buildup and difficulty in inserting the probe. External force is required to impact the probe, which can easily cause it to bend or deform. Deformed probes cannot be straightened manually and reused, affecting normal use. A steel rod straightening machine is usually used for straightening. However, since one end of the probe has a handle, it cannot be removed from the outlet of the straightening device after straightening. Therefore, it needs to be removed from the inlet of the straightening device. The conventional method is to use a flipping motor. However, because the motor rotates quickly, the straightened probe quickly exits the straightening device. If the operator does not catch it in time, the tip of the probe may swing and cause injury.

[0004] Existing technologies disclose several patents for steel bar straightening machines. Among them, utility model patent CN216965887U discloses a steel bar straightening device for steel processing, including a first support, a second support, a third support, and a fourth support. The first support has feed roller brackets installed on both the front and rear sides. Two feed roller support shafts are arranged between the feed roller brackets, and feed rollers are fixedly installed at the middle of each feed roller support shaft. Steel bars are placed between the feed rollers. Water cooling mechanism nozzles are evenly installed at the lower end of the main water cooling mechanism pipe. A cooling water collection tank is located below the fourth support. An impurity baffle is installed inside the cooling water collection tank, and impurity isolation holes are opened on the impurity baffle. A cooling water outlet is located at the bottom of the cooling water collection tank. Although this process straightens bent and deformed steel bars after use, solving the aforementioned technical problem of manual straightening, and facilitating the straightening and reuse of steel bars, the problem of the steel bar retracting too quickly and causing injury, and the inconvenience of removal, still exists when taking the straightened steel bar out of the straightening device.

[0005] In view of this, the inventors conducted in-depth research on this need, which led to the present invention. Utility Model Content

[0006] To overcome the inconvenience of existing technologies where the steel rod needs to be retrieved from the other end of the straightening machine after straightening, and cannot be taken out from the operating end, this utility model provides a straightening device for probe steel rods. The device includes a straightening box and a rectangular support ring fixedly connected inside the straightening box. The support ring includes a top plate and a bottom plate arranged parallel to the upper surface of the straightening box. Both ends of the top plate and the bottom plate are fixedly connected to side plates, and both ends of the top plate and the bottom plate are perpendicularly connected to the side plates. Several traction rollers are respectively arranged in the middle of opposite sides of the top and bottom plates. The traction rollers are rotatably connected to the top plate via connecting rods and fixedly connected to the bottom plate via fixing bolts. A reverse adjustment component for adjusting the direction of the traction rollers is provided at the upper end of the top plate, and the reverse adjustment component is fixedly connected to a connecting piece.

[0007] A reverse adjustment component is installed at the upper end of the top plate. After the steel rod is straightened, the reverse adjustment component adjusts the direction of the traction roller installed at the lower end of the top plate so that the upper and lower traction rollers are in a parallel position. When the traction rollers on the bottom plate and the top plate are parallel to the opposite side plates, the squeezing pressure of the two traction rollers on the straightened steel rod is reduced. The steel rod, which is straightened between the upper and lower traction rollers, can be easily pulled out from the steel rod inlet, avoiding injury to the operator from the swinging end of the steel rod when it is quickly pulled out. It is simple and labor-saving to use.

[0008] Furthermore, the reverse adjustment assembly includes several sector-shaped adjustment gears and a toggle member. The adjustment gears are fixedly connected to the connecting rod and are located on the same side of the top plate. The toggle member passes through the straightening box and is connected to the teeth of the adjustment gear. The toggle member causes the traction roller to turn by moving the adjustment gear.

[0009] Through the above technical solution, the connecting rod fixedly connected to the adjusting gear is rotated by the cooperation of the sector-shaped adjusting gear and the actuating component, thereby causing the traction roller connected to the other end of the connecting rod to rotate in such a direction that the traction rollers located on the bottom plate and the top plate are parallel to each other on the opposite side plates. The steel rod that is straightened between the upper and lower traction rollers can be easily pulled out from the steel rod inlet.

[0010] Furthermore, the actuating component includes a sliding rod and a sliding rack. The two ends of the sliding rod are fixedly connected to the inner wall of the straightening box, and an adjustment groove is provided on the side of the sliding rod near the traction roller. The sliding rack is slidably disposed in the adjustment groove. An adjustment handle is provided at one end of the sliding rack. The end of the adjustment handle passes through the straightening box and is integrally connected to the sliding rack. The sliding rack meshes with the adjustment gear.

[0011] The above technical solution involves fixing the sliding rod to the inside of the straightening box, and sliding a rack that matches the adjusting gear on the sliding rod. By pulling the sliding rack inside the sliding rod with the adjustment handle, the adjusting gear is driven to rotate, thereby achieving the purpose of rotating the traction roller located at the lower end of the top plate.

[0012] Furthermore, the plurality of traction rollers include a U-shaped connector and a straightening roller, the straightening roller being rotatably connected to the open end of the U-shaped connector, the top plate being rotatably connected to the closed end of the U-shaped connector via the connecting rod, and the bottom plate being fixedly connected to the closed end of the U-shaped connector via the fixing bolt.

[0013] The above technical solution connects the pressure rollers at the top and bottom ends with the U-shaped connector. The sliding rack drives the connecting rod to rotate, causing the U-shaped connector to rotate, thus rotating the pressure rollers so that they are parallel to the side plate.

[0014] Furthermore, the connecting rod includes a fixed bearing and a fixed rod. The fixed bearing passes through the top plate and is fixedly connected to the top plate at the middle of its outer side. The fixed rod is fixedly placed in the middle of the fixed bearing. One end of the fixed rod is fixedly connected to the U-shaped connector and the other end is fixedly connected to the adjusting gear. Both ends of the fixed bearing abut against the U-shaped connector and the adjusting gear, respectively.

[0015] Furthermore, limit posts are provided at both sides of the edges of several of the adjusting gears, and the limit posts are fixedly connected to the upper end face of the top plate.

[0016] The above technical solution limits the rotation angle of the rotating wheel by using a limiting post, ensuring that the straightening wheels at both ends can be adjusted to a relatively parallel position, so that the steel rod can be smoothly removed from the device.

[0017] Furthermore, each of the side plates has a straightening hole in the middle. The ends of the two straightening holes near the inner wall of the straightening box are respectively connected to a connecting pipe and a straightening cylinder. The straightening cylinder is located on the same side as the adjusting handle. The free ends of the connecting pipe and the straightening cylinder are fixedly connected to the side wall of the straightening box, and the connecting pipe and the straightening cylinder communicate with the outside of the straightening box.

[0018] By using the above technical solution, the two straightening holes are connected to the connecting pipe and the straightening cylinder respectively, and the connection with the outside of the straightening box is ensured, so that the straightening of the steel rod can be more complete.

[0019] Furthermore, a pulley is provided at one end of the straightening cylinder near the side wall of the straightening box, and a drive motor is provided at the bottom of the straightening box, the drive motor being connected to the pulley via a belt.

[0020] Furthermore, during the straightening of the steel rod, the straightening roller on the base plate and the straightening roller on the top plate are arranged in a staggered and crosswise configuration.

[0021] By using the above technical solution, the traction rollers located on the top plate and bottom plate are tilted relative to the side plate, which can ensure the straightening effect of the steel rod.

[0022] Furthermore, the length of the teeth on the sliding rack ensures that the straightening rollers located on the top plate and the bottom plate are relatively parallel.

[0023] By limiting the length of the teeth on the sliding rack, the straightening rollers at both ends can be adjusted to a relatively parallel position, while also avoiding the waste of space due to an excessively long sliding rack.

[0024] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0025] (1) A reverse adjustment component is set at the upper end of the top plate. The connecting rod fixedly connected to the adjustment gear is rotated by the cooperation of the fan-shaped adjustment gear and the toggle piece. This makes the traction roller connected to the other end of the connecting rod rotate so that the traction rollers on the bottom plate and the top plate are parallel to each other. The steel rod that is straightened in the middle of the upper and lower traction rollers can be easily pulled out from the steel rod inlet, avoiding the steel rod from swinging out of the end and injuring the operator. An external straightening box is added to improve the equipment's rainproof and dustproof performance. It is simple and labor-saving to use.

[0026] (2) Fix the sliding rod to the inside of the straightening box, and slide the sliding rack on the sliding rod to match the adjusting gear. By adjusting the handle, pull the sliding rack in the sliding rod, and the adjusting gear will be rotated through the sliding rack to achieve the purpose of rotating the traction roller located at the bottom of the top plate. It can be adjusted manually according to the needs.

[0027] (3) The structure is simple and easy to use, which solves the problem that the straightening device is inconvenient to take out the steel rod after it has been straightened, thus improving work efficiency. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0035] This embodiment employs a reverse adjustment assembly at the upper end of the top plate. A sector-shaped adjustment gear and a toggle mechanism work together to rotate a connecting rod fixed to the adjustment gear. This causes the traction roller connected to the other end of the connecting rod to rotate in a direction that aligns the traction rollers on the bottom and top plates parallel to their respective side plates. The steel rod, positioned between the upper and lower traction rollers for straightening, can be easily pulled out from its inlet, preventing injury to the operator from the rod swinging out during a quick withdrawal. This method is simple and labor-saving. The specific implementation method is as follows:

[0036] like Figure 1-4As shown, a straightening device for a probe steel rod includes an iron-shell straightening box 1 and a rectangular support ring 2 fixedly connected inside the straightening box 1. A lifting frame is provided at the bottom of the support ring 2 so that it is positioned in the middle of the straightening box 1. The support ring 2 includes a top plate 3 and a bottom plate 4 arranged parallel to the upper surface of the straightening box 1. Both ends of the top plate 3 and the bottom plate 4 are fixedly connected by side plates 5. Both ends of the top plate 3 and the bottom plate 4 are perpendicularly connected to the side plates 5. Several traction rollers 6 are respectively arranged in the middle of the opposite side of the bottom plate 4 and the top plate 3. The traction rollers 6 are rotatably connected to the top plate 3 through connecting rods 7. The traction rollers 6 are fixedly connected to the bottom plate 4 through fixing bolts. A reverse adjustment component 9 for adjusting the direction of the traction rollers 6 is provided at the upper end of the top plate 3. The reverse adjustment component 9 is fixedly connected to the connecting piece.

[0037] Here, a reverse adjustment component 9 is installed on the upper end of the top plate 3. After the steel rod is straightened, the reverse adjustment component 9 adjusts the direction of the traction roller 6 installed on the lower end of the top plate 3 so that the upper and lower traction rollers 6 are in a parallel position. When the traction rollers 6 on the bottom plate 4 and the top plate 3 are parallel to the opposite side plate 5, the squeezing pressure of the two traction rollers 6 on the straightened steel rod is reduced. The steel rod that is straightened in the middle of the upper and lower traction rollers 6 can be easily pulled out from the steel rod inlet, avoiding the steel rod from swinging at the end of the quick-release mechanism and injuring the operator. It is simple and labor-saving to use.

[0038] In a preferred embodiment, the reverse adjustment assembly 9 includes several sector-shaped adjustment gears 10 and actuating element 11. The adjustment gears 10 are fixedly connected to the connecting rod 7 and are located on the same side of the top plate 3.

The actuating element 11 causes the traction roller 6 to turn by actuating the adjustment gears 10.

[0039] Here, the connecting rod 7, which is fixedly connected to the adjusting gear 10, is rotated by the cooperation of the sector adjusting gear 10 and the actuating member 11. This causes the traction roller 6, which is connected to the other end of the connecting rod 7, to rotate in such a direction that the traction roller 6 located on the bottom plate 4 and the top plate 3 is parallel to the opposite side plate 5. The steel rod that is straightened between the upper and lower traction rollers 6 can be easily pulled out from the steel rod inlet.

[0040] In a preferred embodiment, the actuating member 11 includes a sliding rod 12 and a sliding rack 13.

[0041] Here, the sliding rod 12 is fixed to the inside of the straightening box 1, and the sliding rack 13 is slidably set on the sliding rod 12 to match the adjusting gear 10. By adjusting the handle 14, the sliding rack 13 in the sliding rod 12 is pulled, and the adjusting gear 10 is driven to rotate through the sliding rack, thereby achieving the purpose of rotating the traction roller 6 located at the lower end of the top plate 3.

[0042] In addition, a limit nut is fixed to the outside of the straightening box 1 at one end of the sliding rod 12 near the upper adjustment handle 14. The adjustment handle 14 passes through the limit nut and is threadedly connected to the adjustment handle 14. When the adjustment gear 10 is in the steel rod modulation state, the limit nut is threadedly fixed to the adjustment handle 14 to prevent the sliding rack 13 from sliding and causing the adjustment gear 10 to move.

[0043] In a preferred embodiment, a plurality of traction rollers 6 include a U-shaped connector 15 and a straightening roller 16. The straightening roller 16 is rotatably connected to the open end of the U-shaped connector 15. The top plate 3 is rotatably connected to the closed end of the U-shaped connector 15 through a connecting rod 7. The bottom plate 4 is fixedly connected to the closed end of the U-shaped connector 15 through a fixing bolt 8.

[0044] Here, the pressure rollers 16 at the top and bottom ends are connected to the U-shaped connector 15. The sliding rack 13 drives the connecting rod 7 to rotate, causing the U-shaped connector 15 to rotate, thus completing the rotation of the pressure rollers 16 so that they are parallel to the side plate 5.

[0045] In a preferred embodiment, the connecting rod 7 includes a fixed bearing 17 and a fixed rod 18. The fixed bearing 17 passes through the top plate 3 and is fixedly connected to the top plate 3 at the middle of its outer side. The fixed rod 18 is fixedly placed in the middle of the fixed bearing 17. One end of the fixed rod 18 is fixedly connected to the U-shaped connector 15, and the other end is fixedly connected to the adjusting gear 10. Both ends of the fixed bearing 17 abut against the U-shaped connector 15 and the adjusting gear 10, respectively.

[0046] In a preferred embodiment, limit posts 19 are provided on both sides of several adjusting gears 10, and the limit posts 19 are fixedly connected to the upper end face of the top plate 3.

[0047] Here, the rotation angle of the rotating wheel is limited by the limiting post 19, so that the straightening rollers 16 at both ends can be adjusted to a relatively parallel position, so that the steel rod can be smoothly removed from the device.

[0048] In a preferred embodiment, a straightening hole is provided in the middle of each side plate 5. A connecting pipe 20 and a straightening cylinder 21 are respectively connected to one end of each straightening hole near the inner wall of the straightening box 1.

[0051] In a preferred embodiment, when straightening the steel rod, the straightening roller 16 on the bottom plate 4 and the straightening roller 16 on the top plate 3 are arranged in a staggered manner.

[0052] Here, the traction rollers 6 located on the top plate 3 and the bottom plate 4 are tilted relative to the side plate 5 to ensure the straightening effect of the steel rod.

[0053] As a preferred embodiment, the length of the teeth on the sliding rack 13 can ensure that the straightening rollers 16 located on the top plate 3 and the bottom plate 4 are relatively parallel.

[0054] Here, by limiting the length of the teeth on the sliding rack 13, it is ensured that the straightening rollers 16 at both ends can be adjusted to a relatively parallel position, while also avoiding the sliding rack 13 from being too long and wasting space.
