Description

Technical Field

[0001] This utility model relates to the field of glass heating rod technology, and in particular to a glass heating rod height adjustment device. Background Technology

[0002] In the heating of raw materials in chemical, metallurgical and other fields, L-shaped glass heating rods are often used for immersion heating. The vertical section needs to be inserted into the raw material pool, while the horizontal section is used for fixing and connecting the power supply.

[0003] However, as raw materials are consumed or replenished, the liquid level in the tank fluctuates. If the height of the heating rod is fixed and the vertical section is not immersed deep enough, it will cause local overheating of the raw materials or a decrease in heating efficiency. When using manual lifting or simple screw adjustment, there is a lack of self-locking function, and it is easy to be displaced due to vibration or gravity. The lifting guidance is poor, and the heating rod is easy to tilt during the adjustment process, which will lead to leakage or damage at the seal. The center of gravity of the L-shaped structure is off, and ordinary clamps are difficult to hold stably, which poses a risk of falling off. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides a glass heating rod height adjustment device, which effectively solves the problems of uneven heating caused by liquid level changes and displacement caused by the lack of self-locking function in simple screw adjustment.

[0005] This utility model adopts the following technical solution: a glass heating rod height adjustment device, including a base, a concave support frame fixedly connected to the center of the base, a hand-cranked worm gear screw jack fixedly installed on the top of the concave support frame, the hand-cranked worm gear screw jack including a housing, a worm gear and a worm inside the housing meshing with each other, the worm being rotatably connected to the housing through a bearing, one end of the worm extending out of the housing and connected to a hand crank, a vertical screw threaded to the center of the worm gear; square hollow tubes are vertically fixed on both sides of the top of the base, square tubes are slidably inserted into the square hollow tubes, the tops of the two square tubes are connected to a lifting platform, the top of the screw is fixedly connected to the lifting platform, and a glass heating rod clamp is installed on the top of the lifting platform.

[0006] Furthermore, a reinforcing plate is connected between the two square hollow tubes, and the reinforcing plate and the concave support frame are both provided with through slots at the corresponding positions of the lead screw.

[0007] Furthermore, the top of the lead screw is connected to the lifting platform via single and double lugs, which are fixedly connected by bolts.

[0008] Furthermore, the glass heating rod clamp includes two sets of arc-shaped clamps installed on the top of the lifting platform. One side of the arc-shaped clamps is hinged together, and the other side of the arc-shaped clamps is provided with a metal buckle.

[0009] Furthermore, an L-shaped glass heating rod is provided between the two sets of arc-shaped clamps.

[0010] The advantages of this invention are as follows: The hand-cranked worm gear screw jack allows for simple adjustment and operation, enabling users to precisely adjust the height of the glass heating rod as needed, ensuring optimal heating performance under different working conditions. The worm gear transmission has a reverse self-locking characteristic, preventing the lifting platform from sliding down due to gravity and ensuring reliable height locking. The sliding fit between the square tube and the square hollow tube provides bidirectional guidance, avoiding lateral forces on the screw and extending its service life. The hand-cranked crank amplifies torque, enabling minute height adjustments. Single and double lugs connect the screw to the platform, facilitating disassembly and maintenance. The arc-shaped clamp has an openable design compatible with cylindrical, L-shaped, and other irregularly shaped heating rods. The metal locking buckle provides uniform clamping force, preventing the heating rod from loosening. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0017] See Figure 1-3 As shown, a glass heating rod height adjustment device includes a base 1, a concave support frame 2 fixedly connected to the center of the base 1, and a hand-cranked worm gear screw jack 3 fixedly installed on the top of the concave support frame 2. The hand-cranked worm gear screw jack 3 includes a housing 301, in which a worm gear 302 and a worm 303 are meshed with each other. The worm 303 is rotatably connected to the housing 301 through a bearing. One end of the worm 303 extends out of the housing and is connected to a hand crank 304. A vertical screw 305 is threadedly connected to the center of the worm gear 302. Square hollow tubes 4 are vertically fixed on both sides of the top of the base 1. Square tubes 5 are slidably inserted into the square hollow tubes 4. The tops of the two square tubes 5 are connected to a lifting platform 6. The top of the screw 305 is fixedly connected to the lifting platform 6. A glass heating rod clamp 7 is installed on the top of the lifting platform 6. The hand-cranked worm gear screw jack 3 provides precise height adjustment, allowing users to accurately adjust the height of the glass heating rod as needed to ensure optimal heating performance.

[0018] A reinforcing plate 8 is connected between the two square hollow tubes 4. The reinforcing plate 8 and the concave support frame 2 are both provided with through slots 9 at the corresponding positions of the lead screw 305. The reinforcing plate 8 connects the two square hollow tubes 4 to form a rigid frame to resist the torsional load during the lifting process. The through slots 9 provide clearance space for the lead screw 305 to avoid motion interference.

[0019] The top of the lead screw 305 is connected to the lifting platform 6 via single and double lugs 10, which are fixed together by bolts. This makes disassembly, installation and maintenance more convenient, and facilitates the inspection and repair of the equipment in daily use.

[0020] The glass heating rod clamp 7 includes two sets of arc-shaped clamps 71 installed on the top of the lifting platform 6. One side of the arc-shaped clamp 71 is hinged by a hinge 72, and the other side of the arc-shaped clamp 71 is provided with a metal buckle 73, which can be opened and closed flexibly to adapt to heating rods of different sizes, increasing the compatibility of the device and ensuring that the heating rod is firmly fixed during use, preventing the heating rod from loosening due to vibration or external force.

[0021] An L-shaped glass heating rod 11 is provided between the two sets of arc-shaped clamps 71 to ensure that the vertical section of the L-shaped heating rod 10 is always immersed in the raw material, thus avoiding the phenomenon of dry burning of the heating rod due to partial lack of liquid coverage.

[0022] Working principle: Rotating the hand crank 304 drives the worm 303 to rotate. The worm meshes with the worm wheel 302, converting the horizontal rotational motion into the vertical rotation of the worm wheel. The internal thread of the worm wheel 302 engages with the lead screw 305, driving the lead screw to rise and fall vertically. When the lead screw 305 pushes the lifting platform 6, the square tubes 5 on both sides slide synchronously in the square hollow tube 4. The square cross-section restricts the platform rotation, ensuring stability during the lifting process. When the liquid level in the raw material pool drops, the lead screw 305 is adjusted downwards to ensure that the vertical section of the L-shaped heating rod is always immersed in the raw material, avoiding local dry burning. When the liquid level rises, the adjustment is reversed to prevent excessive immersion. The two sets of arc-shaped clamps 71 of the glass heating rod clamp 7 open and close through the hinge 72 and are locked by the metal buckle 73, adapting to heating rods of different widths.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
