[0048] The gas pipe network is arranged on the three-dimensional frame 10 and is assembled along a plurality of shelves 101 in a winding manner. Specifically, in the present embodiment, the gas pipe network is a whole series pipeline. The gas pipe network segments located at each shelf 101 pass through the inside of the shelf 101, and the gas pipe network segments between adjacent shelves 101 are interconnected through the connecting segments arranged along the three-dimensional frame 10, forming a whole series pipeline that is winding and extending. The end of the pipeline is closed, and the head end is connected to the output end of the air pump 30;

[0049] The air pump 30 is disposed on the three-dimensional frame 10, and its output end is connected to the input end of the gas pipe network;

[0050] There are several pressure-maintaining actuators 20, which are arranged in the space between adjacent shelves 101. The pneumatic input end of the pressure-maintaining actuator 20 is connected to the gas pipe network; in this embodiment, Figure 4 It is a partial structural schematic diagram of a pressure-maintaining actuator according to an exemplary embodiment. Figure 5 yes Figure 1 See attached for an enlarged schematic diagram of the structure A. Figure 4-5 The pressure-maintaining actuator 20 includes: a cylinder 203, which is mounted on the bottom end of the shelf 101 of the upper layer and has a gas input port 204; a gas pressure regulating valve 205, which has a first interface connected to the pneumatic input end 204 and electromagnetically controlled to open and close, and a second interface and a third interface connected in series to the gas pipeline network and connected to each other; an upper pressure plate 201, which is fixedly mounted on the telescopic end of the cylinder 203, and a pressure sensor is provided on the upper pressure plate 201; a lower pressure plate 202, which is mounted on the top of the shelf 101 of the current layer, and is arranged in conjunction with the upper pressure plate 201, and the upper end of the lower pressure plate 202 is provided with a symmetrically arranged rear limit block 207 and a front limit block 208 to position and clamp the elevator call box product, and the height of the rear limit block 207 and the front limit piece 208 is less than the thickness of the elevator call box product by 2-3mm; the front limit piece 208 is provided with a piece-out notch 2081 on the upper part of one side facing the rear limit block 207;

[0051] There are several single control panels 206, which are fixed on the shelf 101 and electrically connected to several pressure-maintaining actuators 20 respectively, so as to individually control the pressure-maintaining actuators 20 to glue the glass panels of the elevator call box under pressure.

[0052] In the technical solution of the above embodiment, a plurality of pressure-maintaining actuators 20 are distributed in a matrix on the three-dimensional frame 10, and a single control panel 206 corresponding to the operation of the pressure-maintaining actuator 20 is arranged on the front side thereof, and is used to individually control the pressure-maintaining actuator 20 to pressure-maintain and glue the elevator hall call box glass panel. The integrated setting is convenient for processing personnel to operate in a centralized manner, and a plurality of pressure-maintaining actuators 20 are individually controlled. After a reasonable arrangement of processing time, a small number of processing personnel can sequentially place, maintain pressure and take out a plurality of elevator hall call box glass panel products on one or more three-dimensional frames 10, thereby forming a good processing cycle and improving production efficiency.

[0053] Specifically, taking the operation of a single pressure-maintaining actuator 20 and a single control panel 206 as an example, the elevator call box product after the glass panel is pre-glued is placed between the rear limit block 207 and the front limit block 208 on the lower pressure plate 202 to position the product, and then the single control panel 206 is operated to start the pressure-maintaining actuator 20, the air pressure regulating valve 205 is opened, and the upper pressure plate 201 moves downward to cooperate with the lower pressure plate 202 to clamp the product and pressurize it according to the preset pressure. When the pressure reaches the set value of the pressure sensor, the air pressure regulating valve 205 is closed to maintain the preset pressure to pressurize the elevator call box product, and automatically opens after the preset time is reached to complete the pressure maintenance; this application uses an automatically executed pressure-maintaining actuator 20 to replace the traditional batch stacking pressure maintenance, maintain the stable pressure between the glass panel and the call box, and the glue is firmly bonded, and the damage rate of the glass panel is reduced. Among them, the preset pressure can be achieved by adjusting the air pressure and selecting the model of the cylinder 203. This is a prior art and will not be repeated here.

[0054] In this embodiment, referring to the accompanying drawings, the single control panel 206 has: a pressure-maintaining start button for starting the pressure-maintaining actuator 20; a reset button for manually turning off the pressure-maintaining actuator 20; a timing key group for controlling the execution time of the pressure-maintaining actuator 20; a pressure-maintaining indicator light for indicating the execution status of the pressure-maintaining actuator 20; a power indicator light for indicating the circuit status of the pressure-maintaining actuator 20; further, a PLC controller is provided inside the single control panel 206 to control the start, stop and action of the above-mentioned devices.

[0055] In the technical solution of the above embodiment, taking the operation of a single pressure-maintaining actuator 20 and a single control panel 206 as an example, the elevator call box product after the glass panel is pre-glued is placed between the rear limit block 207 and the front limit block 208 on the lower pressure plate 202 to position the product, and then the pressure-maintaining start button is pressed to start the pressure-maintaining actuator 20, and the upper pressure plate 201 moves downward to cooperate with the lower pressure plate 202 to clamp the product and pressurize it according to the preset pressure, and automatically opens after the preset time is reached to complete the pressure maintenance;

[0056] When the pressure-maintaining actuator 20 has an execution error, that is, a fault, after eliminating the fault, press the reset button and the upper pressing plate 201 moves upward and resets;

[0057] The timing key group is composed of a plurality of keys, and the corresponding time relay is provided in the single control panel 206, which can set the pressure-maintaining execution time of the pressure-maintaining actuator 20, and has an automatic memory function, and the pressure-maintaining execution time is used after setting;

[0058] The pressure-maintaining indicator light changes color when the corresponding single pressure-maintaining actuator 20 fails, making it easy to intuitively find the faulty single pressure-maintaining actuator 20.

[0059] In this embodiment, refer to the attached Figure 4 The facing sides of the upper pressing plate 201 and the lower pressing plate 202 are working surfaces, and the working surfaces are both wooden surfaces, avoiding rigid contact between the upper pressing plate 201 and the lower pressing plate 202 and the elevator call box product (including the glass panel).

[0060] In summary, the elevator outside call box glass panel pressure-maintaining device provided in the embodiment of the utility model uses an automatically executed pressure-maintaining actuator 20 to replace the traditional batch stacking pressure-maintaining, so as to maintain the stable pressurization pressure between the glass panel and the outside call box and ensure the firm glue bonding, thereby ensuring the product fit and reducing the damage rate of the glass panel; at the same time, multiple single pressure-maintaining actuators 20 are integrated in a matrix on the three-dimensional frame 10, and the multiple pressure-maintaining actuators 20 are controlled separately. After reasonably arranging the processing time, a small number of processing personnel can realize the sequential placement, pressure maintenance and removal of multiple elevator outside call box glass panel products on one or more three-dimensional frames 10, forming a good processing cycle, and in this way, optimizing and improving production efficiency.

[0061] Example 2

[0062] The difference between this embodiment and embodiment 1 is that Figure 1-3 As shown, the device also includes a status light 40, which is arranged on the three-dimensional frame 10 and electrically connected to the air pump 30 and a plurality of pressure-maintaining actuators 20; the status light 40 is a three-color indicator light, with red, green and yellow indications.

[0063] In the technical solution of the above embodiment, the three-color indicator light is used to indicate the working status of the air pump 30 and multiple pressure-maintaining actuators 20 on the three-dimensional frame 10. When any state changes, the three-color indicator light changes the indication color and emits an alarm sound. For example, in normal working state, the indication color is green; when the air pump fails, the indication color is red; when any of the multiple pressure-maintaining actuators 20 fails, the indication color is yellow.

[0064] For other structures not described, refer to Example 1.

[0065] In summary, the elevator outside call box glass panel pressure-maintaining device provided in the embodiment of the utility model uses an automatically executed pressure-maintaining actuator 20 to replace the traditional batch stacking pressure-maintaining, so as to maintain the stable pressurization pressure between the glass panel and the outside call box, firmly bond the glue, and reduce the damage rate of the glass panel; at the same time, multiple single pressure-maintaining actuators 20 are integrated in a matrix on the three-dimensional frame 10, and the multiple pressure-maintaining actuators 20 are controlled separately. After reasonably arranging the processing time, a small number of processing personnel can realize the sequential placement, pressure maintenance and removal of multiple elevator outside call box glass panel products on one or more three-dimensional frames 10, forming a good processing cycle, and in this way, optimizing and improving production efficiency.
