[0025] In order to improve the torsion resistance of the hydraulic cylinder transmission rod, the utility model proposes an embodiment of a hydraulic cylinder guide device for a push plate kiln, such as Figure 1As shown, it includes: a guide bracket 10, which is a double-layer bracket, including a slide rail bracket 11 and an elevated bracket 12 arranged below the slide rail bracket 11; a guide trolley 20, including a guide portion 21 and a cross-connection portion 22, wherein the guide portion 21 is horizontally arranged and configured to be directional and movable inside the slide rail bracket 11, and the cross-connection portion 22 is vertically arranged at one end of the guide portion 21, and the bottom end of the cross-connection portion 22 is configured to be detachably connected to the hydraulic cylinder transmission rod.

[0026] Specifically, in the present embodiment, the hydraulic cylinder support conventionally arranged above the crucible outer circulation support is replaced with a guide support 10, and the hydraulic cylinder support is arranged on the same horizontal plane as the crucible outer circulation support, so that the force application line of the hydraulic cylinder transmission rod and the force application line of the crucible are on the same straight line, so as to reduce the generation of torque, and the end of the hydraulic cylinder transmission rod is connected and guided by the guide trolley 20, so that even if torque is generated, it is mainly borne by the guide trolley 20 and the guide support 10, and the hydraulic cylinder transmission rod only bears axial force, thereby greatly improving its torsion resistance and effectively avoiding bending and deformation of the hydraulic cylinder transmission rod.

[0027] In one embodiment, see Figure 2 The slide rail bracket 11 includes: a plurality of horizontal bars 11-1 and vertical bars 11-2, wherein the plurality of horizontal bars 11-1 form a rectangular frame, the plurality of vertical bars 11-2 are arranged perpendicular to the rectangular surface of the rectangular frame, and are arranged side by side on both sides of the long sides and the middle of the rectangular frame to fix the double-row slide rails; a plurality of side slide rails 11-3 are respectively fixed on the plurality of vertical bars 11-2, and a guide channel is provided between the side slide rails 11-3 on two adjacent vertical bars 11-2, and the width of the guide channel is greater than the width of the bridging portion.

[0028] Specifically, in this embodiment, a plurality of cross bars 11-1 are cross-welded to increase the strength of the rectangular frame, and a plurality of vertical bars 11-2 are welded below the rectangular frame to fix the slide rails 11-3. The anti-deformation capability of the slide rails can be controlled by adjusting the spacing between the vertical bars.

[0029] In an optional embodiment, the vertical rod 11 - 2 is configured to be detachably connected to the rectangular frame, and the side slide rail is configured to be detachably connected to the vertical rod 11 - 2 to facilitate movement and maintenance and replacement.

[0030] In one embodiment, please continue to see Figure 2 , each side slide rail 11-3 includes two slide grooves arranged opposite to each other. Specifically, in order to increase the strength of the side slide rails in this embodiment, each side slide rail is composed of two slide grooves, that is, one guide trolley is supported by four slide grooves in total. When the sliding trolley transmits torque, the four slide grooves jointly bear the torque to achieve torque dispersion.

[0031] In one embodiment, the guide portion includes: a rectangular block 21-1 and a plurality of rolling wheel groups or slides 21-2 disposed on both sides of the rectangular block; wherein the rolling wheel group or slide 21-2 on each side is clamped between two oppositely disposed slide grooves, and the width of the rectangular block 21-1 is smaller than the width of the guide channel.

[0032] In one embodiment, a transverse baffle 22-1 is further provided at the bottom of the bridging portion 22. The function of the transverse baffle is to increase the contact area between the bridging portion and the crucible. When only one guide trolley is used, the transverse baffle is required to span the gaps between multiple rows of crucibles to achieve uniform pushing.

[0033] In a preferred embodiment, the utility model will use two guide trolleys 20 arranged side by side to synchronously push two rows of crucibles, and two sets of hydraulic cylinder mechanisms are adaptively required so that the two hydraulic cylinder transmission rods push one guide trolley 20 respectively.

[0034] In one embodiment, a shock-absorbing pad is provided on one side of the transverse baffle plate facing the guide bracket, and the shock-absorbing pad is used to prevent the cross-connection portion from making hard contact with the crucible, thereby preventing the crucible from being damaged.

[0035] In one embodiment, the guide trolley further includes a stopper, which is detachably disposed on the top of the cross-joint portion and has a height exceeding the bottom of the end crossbar of the rectangular frame.

[0038] Specifically, an elastic pad (such as a silicone pad) is arranged between the contact surfaces of the guide portion 21 and the cross-connection portion 22. The silicone pad has a certain supporting force, and then a piezoresistor is arranged in the middle of the elastic pad. When the guide trolley 20 is stuck, the contact surfaces will be close to each other, thereby increasing the pressure on the piezoresistor. When the pressure of the piezoresistor is greater than the preset threshold, the controller 50 controls the alarm 40 to sound an alarm and control the stopping of the operation of the hydraulic cylinder transmission rod. The detachably connected guide portion 21 and cross-connection portion 22 are used to facilitate the above arrangement, wherein, Figure 3 The figure shows the installation positions of the pressure sensor 30, the alarm 40 and the controller 50. Figure 4 The diagram shows the electrical connection relationship between the pressure sensor 30, the alarm 40 and the controller 50. In addition, it should be noted that the controller 50 also needs to be communicatively connected or electrically connected to the controller of the hydraulic cylinder mechanism.

[0039] In one embodiment, the alarm 40 is an audible and visual alarm. Specifically, the audible alarm can remind the user of the occurrence of a fault, and the visual alarm is used to facilitate the location of the fault.

[0040] In one embodiment, the structure of the hydraulic cylinder support is shown in Figure 5 , wherein the height of the hydraulic cylinder support is the same as the height of the crucible external circulation support, or higher than the crucible external circulation, so that the axis of the hydraulic cylinder transmission rod passes through the middle of the crucible placed on the crucible external circulation support to ensure smooth advancement.
