Description

Technical Field

[0001] This utility model relates to the field of old factory building renovation technology, specifically a support device for the structural renovation of old factory buildings. Background Technology

[0002] During the renovation of old factory buildings, it is often necessary to demolish, reinforce, or replace local structures (such as beams and slabs). At this time, a reliable temporary support system must be set up to ensure construction safety.

[0003] Traditional support devices often use screw jacks or steel columns with fixed height combined with wedge-shaped pads for support, which has obvious limitations: First, the height adjustment depends on manual operation, which is inaccurate and inefficient, and makes it difficult to achieve precise synchronous lifting between support points; second, traditional devices cannot actively adapt to the unevenness of the bottom surface of the supported structure, which easily leads to point contact or line contact, resulting in stress concentration and potential safety hazards due to unstable support; third, there is a lack of effective real-time monitoring and feedback mechanisms, and the support status (such as height changes and levelness) depends entirely on periodic manual inspections, which cannot provide timely warnings when the support force decreases or the structure undergoes slight displacement, resulting in insufficient automation and intelligence.

[0004] Therefore, those skilled in the art have provided a support device for the structural renovation of old factory buildings to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a support device for the structural renovation of old factory buildings, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A support device for the structural renovation of an old factory building includes a base, with an adjustment mechanism mounted on top of the base. The adjustment mechanism includes two sets of hydraulic cylinders, the telescopic ends of which are fixedly connected to a support plate. A telescopic rod and a controller body are fixedly connected to the upper surface of the support plate, respectively. A universal ball is fixedly connected to the telescopic end of the telescopic rod, and a universal seat is rotatably connected to the outer surface of the universal ball. A connecting plate is fixedly connected to the upper surface of the universal seat, and two sets of fastening bolts are threaded onto the inner wall of the connecting plate. An infrared distance sensor is fixedly connected to the bottom surface of the support plate, and an electronic level is fixedly connected to the bottom surface of the connecting plate.

[0008] As a further improvement of this utility model: a fixing ring is fixedly connected to the outer surface of the infrared ranging sensor, and the top end of the fixing ring is fixedly connected to the bottom surface of the support plate.

[0009] As a further improvement of this utility model: a reinforcing ring is fixedly connected to the outer surface of each hydraulic cylinder, and the outer surface of each reinforcing ring is fixedly connected to the bottom surface of the support plate.

[0010] As a further improvement of this utility model: the inner wall of the base is threaded with two sets of fixing bolts, and each fixing bolt has a washer fitted on its outer surface, and the bottom end of each washer is in contact with the upper surface of the base.

[0011] As a further improvement of this utility model: two sets of fixing plates are fixedly connected to the outer surface of the telescopic rod, and the bottom surface of each fixing plate is fixedly connected to the upper surface of the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model effectively solves the shortcomings of traditional support devices by setting an adjustment mechanism that integrates hydraulic lifting, universal adaptive leveling and intelligent sensing monitoring. It utilizes two sets of hydraulic cylinders to provide strong and synchronous vertical lifting force, thereby achieving stepless and precise height adjustment.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Please see Figure 1-4 A support device for the structural renovation of an old factory building includes a base 1, with an adjustment mechanism 2 mounted above the base 1. The adjustment mechanism 2 includes two sets of hydraulic cylinders 201, the telescopic ends of which are fixedly connected to a support plate 203. A telescopic rod 206 and a controller body 202 are fixedly connected to the upper surface of the support plate 203, respectively. A universal ball 208 is fixedly connected to the telescopic end of the telescopic rod 206, and a universal seat 207 is rolledly connected to the outer surface of the universal ball 208. A connecting plate 204 is fixedly connected to the upper surface of the universal seat 207, and two sets of fastening bolts 205 are threaded onto the inner wall of the connecting plate 204. An infrared ranging sensor 210 is fixedly connected to the bottom surface of the support plate 203. An electronic level 209 is fixedly connected to the bottom surface of plate 204. The electronic level 209 mainly consists of a tilt sensor core component, a signal processing circuit, a microprocessor, and a display unit. Its working principle is as follows: when the level is placed on the plane being measured, the internal tilt sensor, such as an accelerometer or an electrolyte type, will sense its tilt angle relative to the horizontal plane and convert this physical quantity into an electrical signal. After the electrical signal is amplified and filtered by the signal processing circuit, it is sampled and calculated by the microprocessor, and finally the tilt angle value or directly converted into a horizontal deviation is accurately displayed on the digital display screen. Some models will also indicate the horizontal status through sound or light signals, thereby realizing high-precision, digital level measurement.

[0024] Example 2

[0025] Please see Figure 1-4The outer surface of the infrared ranging sensor 210 is fixedly connected to a fixing ring 7. The top of the fixing ring 7 is fixedly connected to the bottom surface of the support plate 203. The fixing ring 7 is made of metal, and its inner wall is interference-fitted with the outer wall of the sensor or fixed by a set screw to ensure that the sensor remains absolutely stable under the vibration of the equipment operation, and to ensure the accuracy and reliability of the ranging data.

[0026] Each hydraulic cylinder 201 has a reinforcing ring 8 fixedly connected to its outer surface. The outer surface of each reinforcing ring 8 is fixedly connected to the bottom surface of the support plate 203. The reinforcing ring 8 is welded or fixed to the outer wall of the cylinder body of the hydraulic cylinder 201 by flange bolts. Its outer edge is firmly connected to the bottom surface of the support plate 203, which effectively distributes the huge bending moment acting on its root when the hydraulic cylinder is lifted, prevents the connection between the cylinder body and the support plate from being damaged due to stress concentration, and greatly improves the durability and safety of the structure.

[0027] The inner wall of the base 1 is threaded with two sets of fixing bolts 3. Each fixing bolt 3 has a washer 4 on its outer surface. The bottom end of each washer 4 is in contact with the upper surface of the base 1. The fixing bolts 3 are high-strength chemical anchors or expansion bolts. With the help of the enlarged washer 4, the base 1 can be firmly anchored to the concrete foundation or solid ground to prevent the entire device from slipping or overturning when under load, and to ensure the absolute stability of the support.

[0028] Two sets of fixing plates 6 are fixedly connected to the outer surface of the telescopic pole 206. The bottom surface of each fixing plate 6 is fixedly connected to the upper surface of the support plate 203. The fixing plates 6 are symmetrically arranged on both sides of the telescopic pole 206 and are connected to the support plate 203 by welding or bolts, providing additional lateral support for the telescopic pole 206, enhancing its bending stiffness, and ensuring that it remains vertically stable under pressure and does not become unstable.

[0029] A fixed shell 5 is fixedly connected to the outer surface of the controller body 202. The bottom surface of the fixed shell 5 is fixedly connected to the upper surface of the support plate 203. The fixed shell 5 is made of metal plate and has dustproof and splashproof functions, providing physical protection for the internal controller body 202 and its circuits, enabling it to adapt to harsh construction site environments.

[0030] Example 3

[0031] The working principle of this utility model is as follows: In use, the base 1 is first installed securely in the preset support position by fixing bolts 3 and washers 4. The connecting plate 204 is pressed against the bottom surface of the factory building structure to be supported, such as beams or slabs. The device is started by the controller body 202. The controller body 202 can receive remote commands or local operation. First, the controller body 202 controls two sets of hydraulic cylinders 201 to move synchronously, pushing the support plate 203 and its upper components to rise as a whole until the connecting plate 204 is in full contact with the bottom surface of the building structure and a pre-tightening force is applied. During this process, the infrared distance sensor 210 measures the height of the support plate 203 relative to the base 1 or the ground in real time and feeds the data back to the controller body 202 to achieve precise height control. At the same time, the electronic level 209 monitors the levelness of the connecting plate 204 in real time.

[0032] Since the bottom surface of the supported structure may be uneven, the connecting plate 204 will automatically adjust its posture under pressure by the slight rolling of the universal ball 208 under it within the universal seat 207 until it is completely in contact with the bottom surface of the structure. At this time, the electronic level 209 displays a stable but not necessarily absolutely level angle. The controller body 202 can set the level tolerance. If the level exceeds the tolerance after the initial leveling, one or two hydraulic cylinders 201 can be controlled to perform a slight differential lifting and lowering to correct it. When the support posture is adjusted to the optimal position, the fastening bolts 205 can be tightened to lock the relative position of the universal ball 208 and the universal seat 207 to prevent the angle from changing due to vibration during long-term support. The telescopic rod 206 serves as an auxiliary support and shares the force with the hydraulic cylinder 201. During the entire support period, the electronic level 209 and the infrared distance sensor 210 work continuously. Once the controller body 202 detects abnormal settlement of the support height or excessive change in level, it can immediately issue an audible and visual alarm to remind the staff to take appropriate measures, thereby achieving intelligent and highly safe active support.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
