Description

Technical Field

[0001] The utility model relates to a pressing device for a jack, in particular to a device for fixing the jack of a calender in glass production. Background Art

[0002] In the production process of photovoltaic glass, the calender is an important molding equipment. Among them, the molding of the finished glass is affected by many factors, one of the key factors is the side jack. Therefore, the jack equipment supporting the calender is very critical. However, the existing jacks have a relatively high working environment temperature and large pressure changes. The on-site environment will accelerate the fatigue damage of the jack fixing screws. Long-term use will cause the screw fixing to break. The jack cannot be fixed, and the jack cannot be used. The production of glass cannot be stopped, and in severe cases, the jack will be damaged. In addition, due to the high temperature environment at the production site, it cannot be replaced online and can only be replaced offline, causing great losses. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a jack pressing device which has reasonable structural design, reasonable pressure distribution, is not easy to be damaged, works stably and reliably, and is convenient to replace.

[0004] The technical solution adopted by the utility model to solve the above technical problems is a clamping device of the jack, which includes a fixing screw, and the fixing screw fixes the jack head. The structural characteristics are:

[0005] The left clamping hoop is arranged on one side of the jack head and wraps around the jack.

[0006] The side of the jack head;

[0007] A right clamping hoop, which is arranged on the other side of the jack head and wraps around the other side of the jack head;

[0008] The mounting plate is covered on the top of the jack head, the left clamping hoop and the right clamping hoop, and the fixing screw passes through the mounting plate, the left clamping hoop or the mounting plate and the right clamping hoop for fixing.

[0009] Preferably, the number of fixing screws of the utility model is three on one side.

[0010] Preferably, the size of the mounting plate described in the utility model is slightly larger than the size of the jack head, the left compression clamp and the right compression clamp combined.

[0011] Preferably, the mounting plate, the left compression clamp and the right compression clamp described in the present invention have the same thickness.

[0012] Preferably, the mounting plate of the utility model is further provided with structural holes.

[0013] Compared with the prior art, the utility model has the following advantages and effects:

[0014] 1. Due to the installation of left and right clamps, the tension is borne by the whole box instead of the original four corners, which increases the tensile strength and makes the work more stable and reliable.

[0015] 2. The original jack structure does not need to be changed, so the cost is relatively low.

[0016] 3. Effectively prevent downtime losses caused by the breakage of screw fixings and extend the service life of the jack, and add clamps to tighten and fix in a limited space. Prevent downtime losses caused by the breakage of corner screw fixings. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described in detail below in conjunction with the embodiments. The following embodiments are intended to explain the present invention but the present invention is not limited to the following embodiments.

[0023] Embodiment 1:

[0024] like Figures 1 to 3 As shown, this embodiment describes a jack clamping device, which is used in a photovoltaic glass production line. It is used to wrap and strengthen the jack head 1. The jack clamping device consists of a left clamping hoop 2, a right clamping hoop 3, a mounting plate 4, and a fixing screw 5.

[0025] Among them, the left compression hoop 2 and the right compression hoop 3 wrap around the jack head 1, one on the left and one on the right. The left compression hoop 2 and the right compression hoop 3 are of the same shape, both in a U shape. A semi-enclosed structure is formed. The mounting plate 4 covers the top of the jack head 1, the left compression hoop 2, and the right compression hoop 3. The size of the mounting plate 4 is slightly larger than the size of the jack head 1, the left compression hoop 2, and the right compression hoop 3 after being enclosed. The thickness of the mounting plate 4, the left compression hoop 2, and the right compression hoop 3 is the same. The number of fixing screws 5 is three on one side. The fixing screw 5 passes through the mounting plate 4 and the left compression hoop 2 to fix the left compression hoop 2, and the fixing screw 5 passes through the mounting plate 4 and the right compression hoop 3 to fix the right compression hoop 3. In other words, the jack head 1, the left compression hoop 2, the right compression hoop 3, and the mounting plate 4 are fixed as a whole. Considering the structural strength, a structural hole 6 is also provided on the mounting plate 4 .

[0026] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different. All equivalent or simple changes made based on the structure, features and principles described in the concept of the utility model patent are included in the protection scope of the utility model patent. The technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar way, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
