Description

TECHNICAL FIELD

[0001] The utility model relates to a hanging claw furnace field especially relates to a hanging claw furnace righting mechanism. BACKGROUND

[0002] The hanging claw furnace is an important equipment in the field of plate processing, and is often used for heat treatment such as drying of plates. The hanging claw mechanism is used for grabbing, transferring and positioning the plates. During the use of the hanging claw furnace, the plates are closely arranged and moved through the furnace body by the hanging claw mechanism. In order to avoid the mutual abutment of the plates, which leads to the failure of the heat treatment process, and in order to avoid the deformation and deviation of the plates under the high-temperature drying working environment, a righting mechanism is provided to limit and correct the position of the plates in real time, so as to ensure that the plates do not interfere with each other during lifting, entering the furnace and heat treatment, and to avoid the decline of the process quality caused by the position deviation.

[0003] However, the present application inventors found that the above-mentioned technology at least has the following technical problems in the process of implementing the technical scheme of the present application embodiment:

[0004] (1) Low applicability: the conventional righting structure usually adopts rigid clamping arms with fixed spacing, which is difficult to adapt to the size difference of plates of different specifications, resulting in excessive righting gap for narrow plates and ineffective clamping for wide plates, and frequent adjustment of structural parameters is required, which affects the operation efficiency.

[0005] (2) Poor loading compatibility: the opening size of the existing claw device is fixed. In order to fully utilize the space of the hanging claw furnace, the claw design often needs to pursue compactness, resulting in too small claw opening, which makes it easy for the plates to abut against each other and enter the same claw during the loading process, resulting in failure of heat treatment at the abutment.

[0006] In view of the above problems, it is urgent to design a new righting mechanism to realize self-adaptive adjustment of righting gap, compact utilization of space and expansion of loading opening under the premise of ensuring accurate positioning, so as to improve the adaptability of the hanging claw furnace to different working conditions and the overall production efficiency.

[0015] As a preferred embodiment of the present application, the first linear moving part is a ball screw pair, which comprises a first screw shaft and a first ball nut. The first screw shaft is fixedly connected with the output shaft on one side of the double-shaft motor through a shaft coupling. The first ball nut is fixedly connected with a group of righting assemblies.

[0016] As a preferred embodiment of the present application, the second linear moving part is also a ball screw pair, which comprises a second screw shaft and a second ball nut. The second screw shaft is fixedly connected with the other end of the transmission shaft through a shaft coupling. The second ball nut is fixedly connected with another group of righting assemblies.

[0023] The one or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0024] 1. Self-adaptive adjustment of the supporting gap is realized, and the adaptability to different specifications of the plate is improved. Through the reverse synchronous movement of the double-shaft motor driving the ball screw pair on both sides in the synchronous driving assembly, the two groups of supporting assemblies are symmetrically adjusted in distance, and combined with the real-time monitoring of the distance measuring assembly, different wide plates can be accurately adapted. The problem that the traditional fixed clamping arm needs to be frequently adjusted is solved, and the operation efficiency and the universality of the equipment are significantly improved.

[0025] 2. The spatial layout is optimized, and the compactness and utilization rate are enhanced. The sliding connection structure of the supporting assembly and the staggered arrangement of the claws in the claw supporting assembly reduce the internal interference of the mechanism, allowing larger opening design. Combined with the multi-measuring head rapid positioning function of the distance measuring assembly, high-density layout is realized in the limited hoisting claw furnace space, while avoiding the waste of space caused by structural redundancy.

[0026] 3. Adjacent plates are effectively prevented from sticking, and the quality of the heat treatment process is ensured. The first claw and the second claw are arranged in a staggered manner in the height direction, and a side avoiding groove is additionally provided, which expands the area of the guide inclined surface of the claw opening. This design can guide the plate with slight deformation or positioning deviation, prevent multiple plates from being squeezed into the same claw to cause sticking, and thus eliminate the problem of local heat treatment failure caused by sticking.

[0027] 4. Improve the stability and maintenance convenience of the mechanism, and prolong the service life of the equipment. The cover plate protects the synchronous driving assembly and isolates external dust and mechanical interference. The lower end limiting part limits the upward movement distance of the plate to avoid collision risk. This protective design reduces the wear rate of key components and simplifies the daily maintenance process, ensuring long-term stable operation of the equipment. BRIEF DESCRIPTION OF DRAWINGS
