DETAILED DESCRIPTION

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0035] Example:

[0036] See also Figures 1 to 3 , a sliding bearing monitoring device and method, this embodiment is applied to the monitoring of the sliding state of the sliding bearing 5, and the sliding bearing 5 is a unidirectional sliding bridge basin type rubber bearing.

[0037] A sliding support monitoring device includes a conductive unit 1 and a conductive bracket 2, wherein the conductive unit 1 and the conductive bracket 2 are respectively arranged on two relatively sliding support plates of the sliding support 5; the conductive unit 1 includes a plurality of conductive blocks 1.1 arranged along the sliding direction of the sliding support 5, and adjacent conductive blocks 1.1 are separated by insulating members 1.2; the conductive bracket 2 includes a conductive feeler rod 2.1, and the conductive feeler rod 2.1 is in contact and conduction with one of the conductive blocks 1.1; each conductive block 1.1 is connected to the conductive feeler rod 2.1 through a connecting line, and each connecting line is provided with a status display member 3 for displaying the sliding state of the sliding support 5. In this embodiment, the upper support plate 5.1 of the sliding support 5 is fixedly connected to the bridge beam, and the lower support plate 5.2 of the sliding support 5 is fixedly connected to the support pad stone, such as Figure 1 As shown, when the bridge beam slides, the upper support plate 5.1 and the lower support plate 5.2 will slide relative to each other, and the relative position of the conductive contact rod 2.1 and the conductive unit 1 will change, so that the conductive contact rod 2.1 will contact and conduct with different conductive blocks 1.1. Each conductive block 1.1 is connected to a status display element 3, as shown in FIG. Figure 3 As shown, on-site staff can intuitively know the current sliding state of the sliding support 5 through different state display elements 3.

[0038] See also Figure 2The conductive support 2 further comprises a support body 2.2 and an elastic member 2.3; the support body 2.2 is connected to the upper support plate 5.1 or the lower support plate 5.2 of the sliding support 5; the end of the conductive touch rod 2.1 away from the conductive block 1.1 is hinged to the support body 2.2, and the end of the conductive touch rod 2.1 close to the conductive block 1.1 is connected to the support body 2.2 through the elastic member 2.3, and the conductive touch rod 2.1 is pressed against the conductive block 1.1 through the elastic member 2.3. In this embodiment, the support body 2.2 is fixedly connected to the lower support plate 5.2, the conductive unit 1 is installed on the upper support plate 5.1, the elastic member 2.3 is a spring, and the working state of the spring is a compressed state.

[0039] The plurality of conductive blocks 1.1 are symmetrically arranged along the center line of the conductive unit 1, such as Figure 3 As shown, when the upper support plate 5.1 and the lower support plate 5.2 do not slide relative to each other, the contact point of the conductive feeler rod 2.1 abuts against the center line of the conductive unit 1 (that is, the conductive feeler rod 2.1 is in contact with the conductive block 1.1a and the state display element 3a displays the sliding state). In this embodiment, there are five conductive blocks 1.1, which represent the conductive block 1.1a in the normal sliding state of the sliding support 5. The length of the conductive block 1.1a along the sliding direction is the same as the sliding range value of the normal sliding state of the sliding support 5; two conductive blocks 1.1b representing the warning state are symmetrically arranged on both sides of the conductive block 1.1a. When the sliding range of the sliding support 5 exceeds the conductive block 1.1a, the conductive block 1.1b is symmetrically arranged on both sides of the conductive block 1.1a. When the conductive contact rod 2.1 is in contact with the conductive block 1.1b at both ends, the status display unit 3b displays the sliding state, reaching the warning state, and attention should be paid to the sliding state of the sliding support 5 and the bridge beam; the two conductive blocks 3 1.1c representing the dangerous state are respectively arranged at the two ends of the conductive unit 1, and are symmetrical about the center line of the conductive unit 1 (that is, symmetrically arranged about the conductive block 1.1a), and are located on the outside of the conductive block 1.1b. When the conductive contact rod 2.1 is in contact with the conductive block 3 1.1c, the status display unit 3c displays the sliding state, reaching the dangerous state, and the on-site construction personnel need to evacuate in time or take safety precautions. In this embodiment, the sliding range value corresponding to the sliding state of the sliding support 5 is: normal: -80mm~+80mm, warning: -100mm~-80mm or +80mm~+100mm, danger: more than -100mm or more than +100mm (the positive and negative range values ​​are determined relative to the center line of the conductive unit 1. In this embodiment, Figure 3For example, sliding to the left is negative, sliding to the right is positive); the length of the conductive block 1 1.1a along the sliding direction of the sliding support 5 is 160mm, and the length of the conductive block 2 1.1b along the sliding direction of the sliding support 5 is 20mm. In order to improve the versatility of the conductive block 1.1, the specifications of the conductive block 3 1.1c are the same as those of the conductive block 2 1.1b. In this embodiment, when the upper support plate 5.1 and the lower support plate 5.2 do not slide relative to each other, the contact point of the conductive touch rod 2.1 abuts against the center line of the conductive unit 1 (i.e., the center line of the conductive block 1 1.1a), the conductive block 1 1.1a is connected to the status display unit 1 3a, the two conductive blocks 2 1.1b are connected to the same status display unit 2 3b, and the two conductive blocks 3 1.1c are connected to the same status display unit 3c. Figure 3 As shown, the number of status display members 3 can be reduced, thereby reducing the device cost.

[0040] The conductive block 1.1 and the conductive contact rod 2.1 are both made of conductive materials. In this embodiment, the conductive block 1.1 and the conductive contact rod 2.1 are made of copper or aluminum to achieve connectivity of the monitoring circuit.

[0041] The thickness of the insulating member 1.2 along the sliding direction of the sliding support 5 is less than 0.1 mm, so as to avoid the conductive contact rod 2.1 sliding within the thickness range of the insulating member 1.2 for a long time due to the insulating member 1.2 being too thick, and being unable to connect the monitoring circuit, making it inconvenient for on-site personnel to monitor the sliding state of the sliding support 5.

[0042] The insulating member 1.2 is made of plastic or rubber. In this embodiment, the insulating member 1.2 is a rubber sheet with a thickness less than 0.1 mm, which is adhered to the end faces of adjacent conductive blocks 1.1 by structural glue to achieve separation between adjacent conductive blocks 1.1 and avoid affecting the connectivity of the monitoring circuit.

[0043] The status display component 3 is a colored display light, and on-site personnel can intuitively determine the sliding state of the sliding support 5 by the color of the display light. In this embodiment, the status display component 3a connected to the conductive block 1.1a is a green display light, indicating that the sliding support 5 is in a normal sliding state, the status display component 2 3b connected to the conductive block 2 1.1b is a yellow display light, indicating that the sliding support 5 is in a warning sliding state, and the status display component 3 3c connected to the conductive block 3 1.1c is a red display light, indicating that the sliding support 5 is in a dangerous sliding state.

[0044] A sliding support monitoring device also includes a photovoltaic power source 4 connected to the connection line, which is convenient for outdoor operations without the need to lay additional power supply cables.

[0045] A sliding support monitoring method adopts the above-mentioned sliding support monitoring device, and the specific steps are as follows:

[0046] Install the sliding bearing: fix the upper bearing plate 5.1 of the sliding bearing 5 to the prefabricated component, and fix the lower bearing plate 5.2 of the sliding bearing 5 to the bearing pad stone; in this embodiment, the prefabricated component is a bridge beam;

[0047] Setting the conductive blocks: determining the number and specifications of the conductive blocks 1.1 according to the relative sliding range of the upper support plate 5.1 and the lower support plate 5.2 of the sliding support 5;

[0048] Install the sliding support monitoring device: install the conductive unit 1 and the conductive bracket 2 on the two support plates of the sliding support 5 respectively, so that the contact point of the conductive contact rod 2.1 is located on the center line of the conductive unit 1 and contacts the conductive block 1.1 located on the center line of the conductive unit 1;

[0049] Real-time monitoring: The relative sliding between the prefabricated component and the support pad is monitored in real time according to the status display 3 to judge the sliding state of the sliding support 5. The sliding state of the sliding support 5 is divided into three states: normal, warning and dangerous, which correspond to different status display parts 3 and conductive blocks 1.1 respectively. Figure 3 shown.

[0050] In this embodiment, the sliding support 5 is a one-way sliding support, and its sliding direction is perpendicular to the paper surface (such as Figure 1 As shown); when the sliding support 5 is a bidirectional sliding support, two sliding support monitoring devices can be respectively arranged along different sliding directions to monitor the sliding state of the bidirectional sliding support in the left-right direction and the front-back direction, and the compression amount of the elastic member 2.3 in the working state is greater than the maximum sliding amount of the bidirectional sliding support in the left-right direction and the front-back direction, so that the conductive touch rod 2.1 always rests on the conductive block 1.1.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
