Description

Technical Field

[0001] The present application relates to the field of transport equipment, and in particular to a transport vehicle for heat treatment of rolling mill rolls. Background Art

[0002] Rollers are the main working components of a rolling mill that cause continuous plastic deformation of metal. They consist of three main parts: the roll body, the roll neck, and the roll head. The roll body is the middle part of the roll that actually rolls the metal and has a smooth cylindrical or grooved surface.

[0003] Before heat treatment, the rolls are placed on a carriage that holds the heat treatment equipment. The carriage is then moved into the heat treatment equipment, bringing the rolls inside. To maintain the stability of the rolls on the carriage, wedges are typically placed on both sides of the rolls, secured to the carriage.

[0004] However, fixed wedges are difficult to adapt to rollers of different specifications. For rollers of inappropriate specifications, the rollers are prone to shaking on the vehicle body, which may easily lead to safety accidents. Summary of the Invention

[0005] The purpose of this application is to provide a transport vehicle for heat treatment of rollers, which is used to improve the stability of the rollers on the vehicle body and reduce the possibility of safety accidents.

[0006] The present application provides a roller heat treatment transport vehicle that adopts the following technical solution:

[0007] A transport vehicle for heat treatment of rolling mill rolls comprises a vehicle body, wherein a slide groove is provided on the vehicle body, a plurality of support seats are arranged side by side along the slide groove, and the support seats are slidably connected to the vehicle body through the slide groove.

[0008] By adopting the above technical solution, the support seat slides along the slide groove, thereby adjusting the direct pressing distance between adjacent support seats, thereby being able to adjust the distance between adjacent support seats according to different models and specifications of rollers, and then support the rollers, thereby improving the applicability of the vehicle body to different models of rollers. Compared with the support seat in a fixed position on the vehicle body, the movably arranged support seat can quickly adjust the orientation, and there is no need to replace the vehicle body with a support seat in a specific specification position, thereby improving processing efficiency.

[0009] Optionally, the support seat is provided with a plurality of positioning grooves distributed along the surface of the vehicle body perpendicular to the direction of the slide groove, and the positioning grooves are wider at the top and narrower at the bottom.

[0010] By adopting the above technical solution, the end of the roller is clamped in the positioning groove, thereby limiting the position of the roller on the support seat, so that the support seat can stably support multiple rollers, thereby improving the utilization rate of the support seat.

[0011] Optionally, a fixing part is provided between the support seat and the vehicle body, and the fixing part includes a fixing bolt threadedly arranged on the support seat, and one end of the fixing bolt located in the support seat abuts against a fixing block, and the fixing block is slidably connected to the support seat, and one end of the fixing block is set as an inclined surface and abuts against the fixing bolt, and the other end passes through the support seat and abuts against the side wall of the slide groove.

[0012] By adopting the above technical solution, the fixing bolt is rotated so that the fixing bolt moves toward the side where the vehicle body is located, and the fixing bolt squeezes the fixing block. The fixing block moves in the direction of separation from the support seat under the push of the fixing bolt until it is pressed against the side wall of the slide groove, thereby fixing the support seat to the vehicle body. The fixing bolt is rotated in the opposite direction so that the fixing bolt no longer presses the fixing block against the side wall of the slide groove, so that the support seat can move along the slide groove again, thereby adjusting the position of the support seat.

[0013] Optionally, a return spring is further provided inside the support seat, one end of the return spring is connected to the support seat, and the other end is connected to the fixed block.

[0014] By adopting the above technical solution, when the fixed block is pressed against the side wall of the slide groove, the return spring is in a stretched state. In the process of the fixing bolt moving away from the vehicle body, the return spring pulls the fixed block toward the inside of the support seat, gradually separating from the side wall of the slide groove, thereby reducing the possibility of hindering the movement of the support seat.

[0015] Optionally, a moving mechanism for moving the rollers is provided on the vehicle body.

[0016] By adopting the above technical solution, when the rolling roller moves to a positioning slot on the support seat, the moving mechanism moves the rolling roller to the next adjacent positioning slot, and then the next rolling roller is placed in the empty positioning slot. As a result, the rolling roller is placed at the same position on the support seat each time and moved to the next positioning slot in turn, thereby facilitating the placement of the rolling roller and improving the placement efficiency.

[0017] Optionally, the moving mechanism includes a plurality of first connecting rods arranged on the vehicle body, the first connecting rods are rotatably connected to the vehicle body, and one first connecting rod is arranged between two adjacent positioning slots, the end of the first connecting rod away from the base is hinged to the same second connecting rod, and a top support is provided on the second connecting rod, the number of the top supports is the same as the number of the positioning slots, and a driving member is also provided on the base.

[0018] By adopting the above technical solution, the driving member drives a first connecting rod to rotate, the first connecting rod drives the second connecting rod to translate, and at the same time causes the remaining first connecting rods to rotate accordingly. The supporting member on the second connecting rod lifts up the roller in the positioning groove during the upward movement, and then moves the roller to the next adjacent positioning groove during the downward rotation, thereby realizing the movement of the roller and improving the placement efficiency of the roller.

[0019] Optionally, the driving member includes a driving motor disposed on a base, and an output shaft of the driving motor is connected to one of the first connecting rods.

[0020] By adopting the above technical solution, when the vehicle body is located outside the heat treatment equipment, the drive motor is installed on the base, and the output shaft of the drive motor is connected to the first connecting rod, thereby driving the first connecting rod to rotate. When the vehicle body needs to enter the interior of the heat treatment equipment, the drive motor is removed from the base, thereby reducing the possibility of the drive motor being damaged due to entering the heat treatment equipment.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The support seat slides along the slide groove to adjust the distance between adjacent support seats. This allows the distance between adjacent support seats to be adjusted according to different types and specifications of rollers, thereby supporting the rollers and improving the applicability of the car body to different types of rollers.

[0023] 2. When the roller moves to a positioning slot on the support seat, the moving mechanism moves the roller to the next adjacent positioning slot, and then the next roller is placed in the empty positioning slot. In this way, the roller is placed at the same position on the support seat each time and moved to the next positioning slot in turn, thereby facilitating the placement of the roller and improving the placement efficiency.

[0028] Example: A transport vehicle for heat treatment of rollers, referring to Figure 1 and Figure 2The vehicle comprises a vehicle body 1, with rollers mounted on the lower side of the vehicle body 1 and tracks disposed below the rollers. Two parallel chutes 11 are formed on the upper side of the vehicle body 1. The cross-section of the chutes 11 is configured as an inverted T. Along the length of the chutes 11, the vehicle body 1 is provided with a plurality of parallel support seats 2. Slide blocks 21 corresponding to the chutes 11 are disposed below both ends of the support seats 2. The slide blocks 21 are slidably connected within the chutes 11.

[0029] The support seat 2 slides along the slide groove 11, thereby adjusting the distance between adjacent support seats 2. In this way, the distance between adjacent support seats 2 can be adjusted according to different models and specifications of rollers, thereby supporting the rollers, thereby improving the applicability of the vehicle body 1 to different models of rollers.

[0030] The support base 2 is provided with a plurality of positioning slots 22, which are evenly distributed along the length of the support base 2 and gradually decrease in size from top to bottom. The ends of the rollers are engaged in the positioning slots 22, thereby limiting the position of the rollers on the support base 2, so that the support base 2 can stably support multiple rollers.

[0031] A fixing member 3 is provided between the support base 2 and the vehicle body 1. The fixing member 3 includes a fixing bolt 31 threadedly mounted on the support base 2. One end of the fixing bolt 31 is located within the slider 21, and fixing blocks 32 are abutted on both sides of the end of the fixing bolt 31 located within the slider 21. The side of the fixing block 32 abutting the fixing bolt 31 is configured as an inclined surface. The fixing block 32 is slidably connected to the support base 2. The end of the fixing block 32 away from the fixing bolt 31 extends through the support base 2 and abuts against the side wall of the slide 11. A return spring 33 is also provided within the support base 2, located between the two fixing blocks 32, and connecting both fixing blocks 32.

[0032] The locking cam 33 is engaged with the locking cam 32 and the spring 33 is engaged with the locking cam 32 so that the cam 32 is engaged with the locking cam 32 and the locking cam 32 is engaged with the locking cam 32.

[0033] The body 1 is provided with a groove 12 parallel to the support base 2. A moving mechanism 4 for moving the rollers is provided within the groove 12. The moving mechanism 4 includes multiple first connecting rods 41 provided on the body 1. A first connecting rod 41 is provided between two adjacent positioning grooves 22. One end of the first connecting rod 41 is rotatably connected to the body 1. All first connecting rods 41 are hingedly connected to the same second connecting rod 42 at their ends away from the body 1. The second connecting rod 42 is provided with a top support 43 corresponding to each of the first connecting rods 41. A driving member is also provided on the base. The driving member can also be provided as a drive motor that can be detachably mounted on the base, with the output shaft of the drive motor connected to one of the first connecting rods 41.

[0034] When the rolling roller moves to a positioning slot 22 on the support seat 2, the driving motor drives a first connecting rod 41 to rotate, and the first connecting rod 41 drives the second connecting rod 42 to move horizontally, while causing the remaining first connecting rods 41 to rotate accordingly. The supporting support 43 on the second connecting rod 42 lifts the rolling roller in the positioning slot 22 during the upward movement, and then moves the rolling roller to the next adjacent positioning slot 22 during the downward rotation, thereby realizing the movement of the rolling roller. Each time the rolling roller is moved, it is placed at the same position on the support seat 2 and moved to the next positioning slot 22 in turn, thereby facilitating the placement of the rolling roller and improving the placement efficiency.

[0035] In addition, when the vehicle body 1 is located outside the heat treatment equipment, the drive motor is installed on the base, and the output shaft of the drive motor is connected to the first connecting rod 41, thereby driving the first connecting rod 41 to rotate. When the vehicle body 1 needs to enter the interior of the heat treatment equipment, the drive motor is removed from the base, thereby reducing the possibility of the drive motor being damaged due to entering the heat treatment equipment.

[0036] The implementation principle of the embodiment of the present application is: according to the specifications of the rolling roller, the position of the support seat 2 is moved. After the position of the support seat 2 is determined, the fixing bolt 31 is rotated to fix the support seat 2, and the rolling roller is placed on a positioning groove 22 of the support seat 2. Then, the driving motor drives the first connecting rod 41 to rotate, and the second connecting rod 42 drives the top support 43 to move, thereby moving the rolling roller, thereby translating the rolling roller in turn to quickly achieve the placement of the rolling roller.
