Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for refractory material masonry in metallurgical furnaces and kilns, and specifically to a lead screw with a thread cleaning device. Background Technology

[0002] In the construction of refractory materials for metallurgical furnaces and kilns, the lead screw is one of the most critical tools. The construction of metallurgical furnaces and kilns involves the use of large quantities of water-containing refractory mortar and other materials. As a temporary support structure for the refractory masonry, the lead screw must frequently bear the weight of the masonry and maintain stability, inevitably exposing its threaded portion to this complex and harsh environment. During actual operation, impurities such as sludge easily accumulate at the lead screw threads. This sludge is mainly composed of solid particles remaining after the water in the refractory mortar evaporates, dust from the furnace / kiln, and other impurities in the air. During continuous use of the lead screw, sludge will continuously accumulate at the threads. Currently, these impurities are mainly cleaned manually using tools such as wire brushes, which not only requires a significant amount of manpower and time, but also, due to the complexity of the thread structure, it is difficult to completely remove impurities deep within the thread gaps. Residual impurities can have many adverse effects on the normal use of the lead screw: on the one hand, impurities can damage the thread fit accuracy, causing problems such as jamming and lack of smoothness in the transmission between the lead screw and the lead screw sleeve, affecting the stability and reliability of the support; on the other hand, long-term residue of impurities will accelerate the wear of the threads, shorten the service life of the lead screw, and increase the equipment replacement cost and maintenance difficulty. Utility Model Content

[0003] To address the problem of difficulty in cleaning impurities from threads in the existing technology, this utility model provides a lead screw with a thread cleaning device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A lead screw with a thread cleaning device includes a threaded rod, a lead screw sleeve, a support plate, and the thread cleaning device. One end of the threaded rod is connected to the support plate, and the threaded rod is perpendicular to the surface of the support plate. The other end of the threaded rod is disposed inside the lead screw sleeve. The inner wall of the lead screw sleeve is provided with an internal thread that matches the threaded rod. The thread cleaning device is disposed at the top of the lead screw sleeve. The thread cleaning device includes a fixed seat, a connecting part, a cleaning part, and a support seat. The fixed seat is disposed at the top of the lead screw sleeve. One end of the connecting part is connected to the fixed seat, and the other end is connected to the cleaning part. The shape of the cleaning part matches the root of the threaded rod thread, and the cleaning part abuts against the root of the threaded rod thread. The support seat is disposed at the top of the lead screw sleeve, and the support seat is disposed on the side opposite to the force direction of the fixed seat.

[0006] Furthermore, the surface of the cleaning section is provided with several protrusions.

[0007] Furthermore, the connecting part includes a fixing part, a telescopic part, and a locking device. The fixing part is connected to the fixing seat, the telescopic part is connected to the cleaning part, the fixing part is connected to the telescopic part, and the locking device is disposed on the fixing part.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model provides a lead screw with a thread cleaning device. The thread cleaning device is installed on the top of the lead screw sleeve. The operator can adjust the extension length of the telescopic part according to actual needs, so that the cleaning part is tightly pressed against the root of the thread of the lead screw. When the lead screw retracts into the lead screw sleeve, the cleaning part can simultaneously clean the impurities in the thread, realizing real-time removal of impurities in the lead screw during use. This avoids the long-term accumulation and hardening of impurities in the thread, effectively ensuring the thread fit accuracy between the lead screw and the lead screw sleeve, ensuring the smoothness and stability of the lead screw transmission process, significantly reducing the probability of problems such as thread jamming and wear caused by impurities, extending the service life of the lead screw, reducing equipment replacement and maintenance costs, and improving the efficiency and quality of refractory material masonry operations.

In order to prevent the fixed seat from being displaced or broken after being subjected to force, the support seat is set on the side opposite to the force direction of the fixed seat.

The locking device is disposed on the fixing part and is used to fix the relative position of the telescopic part and the fixing part after the telescopic part extends and retracts to a suitable position.

[0020] In one embodiment of this utility model, the thread cleaning device 4 and the lead screw sleeve 2 are connected by bolts.

[0021] In one embodiment of this utility model, an elastic buffer is provided between the support base and the top of the lead screw sleeve 2. The elastic buffer is used to buffer the force on the support base.

[0022] In use, the thread cleaning device 4 is installed on the top of the lead screw sleeve 2, and the extension length of the telescopic part is adjusted so that the cleaning part is against the root of the thread of the thread rod 1. When the thread rod 1 retracts into the lead screw sleeve 2, the cleaning part removes the impurities in the thread, realizing real-time cleaning of impurities in the thread rod during use.

[0023] This utility model provides a lead screw with a thread cleaning device. The thread cleaning device is installed on the top of the lead screw sleeve.
