Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transportation auxiliary tools technology, specifically relating to a transshipment device. Background Technology
[0002] With the continuous development of the steel industry, blast furnaces, as crucial equipment in steel production, play a vital role in the entire production process through their operational efficiency and safety. During blast furnace operation, the replacement and maintenance of the tuyere system are unavoidable tasks, particularly the frequent disassembly and replacement of the air supply branch pipes. However, traditional replacement methods present numerous inconveniences, especially in work areas with limited space at the tuyere platform and restricted forklift access.
[0003] Traditional methods for replacing air supply branch pipes primarily rely on hoists and other lifting tools. This method is not only time-consuming and labor-intensive, requiring highly skilled operators, but also inefficient due to the large number of branch pipes to be replaced, tight deadlines, and heavy workload, where hoisting and installation interfere with each other. Furthermore, the weight and size of the air supply branch pipes make traditional handling methods prone to damaging equipment and posing safety hazards to operators.
[0004] Therefore, there is a need for a simple-to-operate transfer device that can easily and quickly transfer the air supply branch pipes and improve replacement efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a transfer device that is easy to operate and can conveniently and quickly transfer the air supply branch pipes, improving replacement efficiency. At the same time, it can adapt to environments with small air outlet platforms, reduce reliance on hoisting equipment, and improve the safety and convenience of operation.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A conveying device includes a movable support, push-pull rods respectively disposed at the front and rear ends of the movable support, and an adjustable clamp for supporting the air supply branch pipe; the movable support includes crossbars disposed at the front and rear and symmetrically provided with casters at both ends of the bottom, and vertical rods disposed on the left and right and respectively connected to the two crossbars; the adjustable clamp includes two sliding plates respectively disposed laterally on the crossbar at the rear end of the movable support, and two clamping plates respectively disposed laterally and vertically on the two sliding plates to support the air supply branch pipe; the opposite ends of the two sliding plates are respectively provided with positioning components adapted to the crossbar at the rear end of the movable support.
[0008] A further improvement of this utility model is that: the tops of the two card plates are symmetrically provided with arc-shaped grooves suitable for the outer wall of the air distribution branch pipe. When the two card plates move relative to each other and abut against each other on the crossbar at the rear end of the movable bracket via the sliding plate, the arc-shaped grooves on the tops of the two card plates can form a semi-circular arc-shaped card slot.
[0009] A further improvement of this utility model is that a groove is provided on the crossbar at the rear end of the movable support along its length, and the two slide plates are slidably connected to the groove by sliders set at their bottoms.
[0010] A further improvement of this utility model is that: a number of positioning holes are evenly spaced along the length of the crossbar at the rear end of the movable support, and the virtual line formed by each positioning hole is parallel to the slide groove.
[0011] A further improvement of the present invention is that the positioning component includes a positioning pin that is connected to the top of the slide plate via a chain and is adapted to the positioning hole, and a through hole adapted to the positioning pin is provided on the slide plate along its thickness direction.
[0012] A further improvement of the present invention is that the push-pull rod includes a connecting rod at the bottom that is hinged to the crossbar at the front end of the movable bracket via a pin, and a grip rod set at the top of the connecting rod.
[0013] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:
[0014] This utility model of a reversing device is easy to operate and can conveniently and quickly reverse the air supply branch pipe, improving replacement efficiency. At the same time, it can adapt to environments with small air outlet platforms, reduce dependence on equipment, and improve the safety and convenience of operation.
[0015] The adjustable clamp used in this utility model includes two sliding plates that can slide laterally on the crossbar at the rear end of the movable support, and two clamping plates that are respectively horizontally and vertically arranged on the two sliding plates to support the air supply branch pipe. The top of the two clamping plates is symmetrically provided with arc-shaped grooves that are adapted to the outer wall of the air supply branch pipe. The two clamping plates can be moved and adjusted along the length direction of the crossbar at the rear end of the movable support under the drive of the sliding plates. The two clamping plates can move in the same direction or move relative to each other. By moving on the crossbar, the distance between the two clamping plates can be adjusted to adapt to air supply branch pipes of different diameters.
[0016] The present invention employs a movable support with crossbars arranged in a front-to-back configuration and symmetrically equipped with casters at both ends of the bottom, as well as vertical bars arranged on the left and right sides and connected to the two crossbars respectively. Therefore, it can move flexibly and adapt to various working environments, especially in areas with limited space. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to embodiments:
[0022] like Figure 1 and Figure 2 As shown, this utility model provides a conveying device, including a movable support 1, a push-pull rod disposed at the front end of the movable support 1, and an adjustable clamp disposed at the rear end of the movable support 1 for supporting the air supply branch pipe. Specifically, the movable support 1 includes two horizontal bars and two vertical bars. The two horizontal bars are arranged front and rear correspondingly, and the two vertical bars are arranged left and right correspondingly. The two vertical bars are respectively connected to the two horizontal bars, making the movable support 1 in a "U" shape. Universal wheels are symmetrically provided at both ends of the bottom of the two horizontal bars, allowing the movable support 1 to move flexibly. The push-pull rod includes a connecting rod 9 and a handle 10. The bottom of the connecting rod 9 is hinged to the horizontal bar at the front end of the movable support 1 via a pin 2, allowing it to rotate up and down for easy pushing and pulling. The handle 10 is disposed at the top of the connecting rod 9.
[0023] Furthermore, the adjustable clamp is a split structure, comprising two sliding plates 4 and two cooperating clamping plates 3 supporting the bottom of the air supply branch pipe. The two sliding plates 4 are respectively slidably mounted on the crossbar at the rear end of the movable bracket 1. Specifically, a groove 5 is provided along the length of the crossbar at the rear end of the movable bracket 1, and the two sliding plates 4 are slidably connected to the groove 5 on the crossbar by sliders provided at their bottoms.
[0024] Two clamping plates 3 are respectively horizontally and vertically mounted on two sliding plates 4. Therefore, the two clamping plates 3 can be moved and adjusted along the length of the crossbar at the rear end of the movable support 1 under the action of the sliding plates 4. The two clamping plates 3 can move in the same direction or move relative to each other. By moving on the crossbar, the distance between the two clamping plates 3 can be adjusted to accommodate air supply branch pipes of different diameters. Specifically, the top of the two clamping plates 3 is symmetrically provided with arc-shaped grooves 3-1 adapted to the outer wall of the air supply branch pipe. The arc-shaped grooves 3-1 are opened from the top of the clamping plates 3 to one side wall of the clamping plates 3. Preferably, the arc of the arc-shaped grooves 3-1 is 90°, that is, a quarter-circle arc. When the two clamping plates 3 move relative to each other and abut against each other on the crossbar at the rear end of the movable support 1 via the sliding plates 4, the arc-shaped grooves 3-1 on the top of the two clamping plates 3 can form a semi-circular arc-shaped clamping groove.
[0025] In order to limit the two adjusted plates 3, positioning components are respectively provided at the opposite ends of the two slide plates 4, and the positioning components are adapted to the crossbar at the rear end of the movable bracket 1. After the two plates 3 have been adjusted by moving on the crossbar through the slide plate 4, they can be limited on the crossbar by the positioning components on the slide plate 4. Then the operator can use the lifting equipment to lift the air supply branch pipe onto the movable bracket 1 and support it by the two cooperating plates 3.
[0026] Specifically, a number of positioning holes 6 are provided on the crossbar at the rear end of the movable support 1. These positioning holes 6 are evenly spaced along the length of the crossbar, and the virtual line formed by the positioning holes 6 is parallel to the sliding groove 5 on the crossbar. For example... Figure 3 As shown, the positioning component includes a positioning pin 8. The top of the positioning pin 8 is connected to the top of the slide plate 4 via a chain 7. The slide plate 4 has a through hole adapted to the positioning pin 8 along its thickness direction. The positioning pin 8 is adapted to the positioning hole 6 opened on the crossbar at the rear end of the movable bracket 1. When the card plate 3 is limited, the positioning pin 8 can pass through the through hole on the slide plate 4 and be inserted into the appropriate positioning hole 6 on the crossbar at the rear end of the movable bracket 1, thereby achieving the purpose of limiting.
