Description

Technical Field

[0001] The utility model relates to the technical field of hot saw machines, in particular to a novel saw door moving device. Background Art

[0002] When producing large-sized round steel, hot saws are used to perform segmented sawing operations. The saw door moves back and forth with the hot saw to block sawdust and cooling water. In the prior art, the saw door adopts a single-sided suspension device, which is clamped on the track by two V-shaped wheels. The bottom uses a pin to connect the saw door and the base to form a two-way fixation for the saw door. This design is mainly based on two considerations. On the one hand, it is convenient to disassemble the saw door. When the saw door needs to be disassembled, the pin is pulled out, and the saw door is pushed to drive the V-shaped wheel to disengage from the track, so that the saw door can be disassembled; on the other hand, it is to reduce the polarization phenomenon of the saw door during movement. Due to the large size of the saw door, if the saw door is only fixed to the base at one place, the saw door is prone to obvious polarization during movement, which will cause the saw door to deform over time.

[0003] The current technical problems are: in the initial stage of use, due to the good on-site environment, the saw door was not deformed and could operate normally. After being put into use for a period of time, sawdust will inevitably accumulate in the saw door guide groove, and the saw door will be deformed due to long-term use, vibration and other reasons, and the center of gravity will change. When it continues to be used, on the one hand, the saw door will have an eccentric suspension phenomenon, and the V-shaped wheel will be subjected to eccentric force when moving, and the bearing will be easily damaged. On the other hand, due to the accumulation of iron oxide in the saw door guide groove, the saw door will encounter iron oxide during movement and cause jamming. The V-shaped wheel cannot be hung stably on the track, which will cause the V-shaped wheel to run out of the track, causing the saw door to fall. This failure will directly affect production. Maintenance personnel need to work at high altitude during emergency repairs, and the working surface is small, the emergency repair work has high safety risks and high labor intensity.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figure 1-Figure 2 The utility model provides a technical solution: a novel saw door moving device, comprising: a base 7 for installing a hot saw, the base 7 is located outside a saw box 6, and the base 7 moves on the cutting route of the round tube, so that the hot saw cuts the round tube; a saw door 2 and a connecting piece connecting the saw door 2 and the base 7, the saw door 2 is used to separate the cutting environment in the saw box 6 from the environment outside the saw box 6 when cutting the round tube; in this embodiment, the connecting piece is a latch;

[0027] The device further comprises: a first track arranged on the top of the saw box 6, a connecting plate arranged on the top of the saw door 2, and a supporting member arranged on one side of the connecting plate; the supporting member is clamped on the first track, used to support the saw door 2, and when the saw door 2 moves, the supporting member moves along the first track; in this embodiment, the supporting member is a guide wheel 1 clamped on the first track, and the guide wheel 1 is rotatably arranged on one side of the connecting plate;

[0028] The above technical solution can be used to suspend the saw door 2 on one side and can move horizontally synchronously with the base 7. During operation, the base 7 moves on the cutting path of the round tube so that the hot saw can cut the round tube. During the movement of the base 7, the base 7 will drive the saw door 2 to move synchronously, thereby driving the guide wheel 1 to slide on the first track. The saw door 2 moves back and forth with the hot saw to block sawdust and cooling water.

[0029] As the main improvement of the utility model, the new saw door moving device also includes a plurality of support frames arranged on the top of the saw box 6; a second track 4 connected to the support frame; a hanging member arranged on the other side of the connecting plate, the hanging member is clamped on the second track 4, and is used to cooperate with the support member to balance the saw door 2 together; in this embodiment, the support frame is a bracket 5 with one end arranged on one side of the first track, and the other end of the bracket 5 is installed with a channel steel, and the channel steel is used to install and fix the second track 4; the hanging member is a V-shaped wheel 3 clamped on the second track 4, and the V-shaped wheel 3 rotates the other side of the connecting plate, so that the saw door 2 is balanced and suspended between the two tracks through the guide wheel 1 and the V-shaped wheel 3 shown;

[0030] The adoption of the above technical solution can further improve the stability of the saw door 2. The principle is to add a second track 4 and a suspension part on the basis of the original first track and support part, and improve the original saw door 2 from a single-sided suspension to a double-sided suspension, so that the saw door 2 has strong impact resistance and eliminates unbalanced load. At the same time, because the V-shaped wheel 3 is added, when the guide wheel 1 of the first suspension component is desoldered, the V-shaped wheel 3 of the second suspension component can still maintain the normal operation of the saw door 2. Since the saw door 2 is supported on both sides, the saw door 2 is prevented from falling or bearing damage, thereby reducing the failure rate of the saw door moving device.

[0031] Furthermore, the bracket 5 is fixed to the upper end of the saw box 6 by welding, and the bracket 5 is designed to be removable, and is connected in the middle by flange bolts. In this embodiment, the bracket 5 adopts a gantry bracket;

[0032] The above technical solution is adopted to facilitate the disassembly and assembly of the bracket 5 during later maintenance.

[0033] Further, the support member and the suspension member are arranged in pairs to form a suspension mechanism, and there are multiple suspension mechanisms, and the suspension mechanisms are arranged at the upper end of the saw box 6 along the first track or the second track 4;

[0034] The adoption of the above technical solution can further improve the stability of the saw door 2. By increasing the number of the first suspension assembly and the second suspension assembly, the number of guide wheels 1 and V-shaped wheels 3 is also increased accordingly. When some guide wheels 1 or V-shaped wheels 3 are desoldered, other guide wheels 1 or V-shaped wheels 3 can still maintain the normal operation of the saw door 2. There is a certain time margin for maintenance personnel to discover abnormalities, which is safer and more reliable.

[0035] Working principle: By adding a second track 4 and a suspension part on the basis of the original first track and support part, the saw door 2 is improved from the original single-sided suspension to a double-sided suspension, which makes the saw door 2 highly impact-resistant and eliminates unbalanced loads. At the same time, because of the addition of the suspension part, when the support part is desoldered, the suspension part cooperates with the second track 4 to maintain the normal operation of the saw door 2. There is a certain time margin for maintenance personnel to discover abnormalities and prevent the saw door 2 from falling, thereby reducing the failure rate of the saw door moving device.

[0036] Thereby completing a series of tasks, the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
