The invention discloses a mobile pipe jacking anti-retreat bracket device and a method for preventing retreat, comprising a pair of anti-retreat supports respectively arranged on both sides of the pipe joint jacking direction, and used for the anti-retreat support brackets to be pushed along a direction perpendicular to the pipe joint. The guide rail of the bracket that moves in the direction; the inner side of the rear end of the anti-retraction bracket on both sides is respectively provided with a mechanical locking device for restricting the retreat of the pipe joint; Telescopic rod device; when the pipe joint advances in the direction of jacking, it first contacts and compresses the mechanical locking devices on both sides until the entire pipe joint passes, and the mechanical locking device rebounds and resists the rear end of the pipe joint to limit The pipe joint retreats; at the same time, the mobile hydraulic telescopic rod device can move to the position of the hoisting hole reserved on the side wall of the pipe joint, and insert the pin shaft into the hoisting hole to stop the pipe joint from retreating.

An anti-falling device for a hydraulic decoking system, comprising a lifting mechanism, a lever mechanism, a locking mechanism, a guiding mechanism and a bracket, the two sides of the bracket are provided with locking guide rails for guiding the vertical movement of the bracket, and the bracket is provided with The guide mechanism matched with the locking guide rail, the lifting mechanism is arranged on the top of the bracket, the lifting mechanism is provided with a lifting rod, and the lifting rod passes through the through hole set on the bracket downwards, and passes through the lever mechanism fixed on the bracket and the lock. The tension mechanism is connected, and the lifting rod is located between the lever mechanism and the bracket, and a return spring is sleeved. The return spring can push the lever mechanism to move when the lifting mechanism falls, and make the locking mechanism contact the locking guide rail. The invention has the advantages of simple structure, reasonable design, low manufacturing cost, long continuous trouble-free operation period, high safety reliability, and low device cost, effectively preventing accidental injuries to operators due to equipment falling.

An anti-dropping device for a hydraulic decoking system comprises a lifting mechanism, a lever mechanism, a locking mechanism, a guide mechanism and a support. Locking guide rails for guiding the support to perform vertical motion are arranged on two sides of the support, the support is provided with the guide mechanism matched with the locking mechanism, the lifting mechanism is arranged at the top end of the support and provided with a lifting rod, the lifting rod penetrates a through hole in the support downwards and is connected with the locking mechanism through the lever mechanism fixed on the support, the part of the lifting rod located between the lever mechanism and the support is sleeved with a returning spring, the returning spring can push the lever mechanism to move when the lifting mechanism drops, and the returning spring enables the locking mechanism to be in contact with the locking guide rails. The anti-dropping device is simple in structure, reasonable in design, low in processing and manufacturing cost, long in continuous failure-free running cycle, high in safety reliability and low in device cost, and accidental injury accidents caused to operators due and caused by device dropping are effectively avoided.

A laminating device increases raising speed of laminating speed without a temperature detector and stably sustains the laminating temperature. The laminating device is provided with the following components: a thermal compression bonding transmission device (10) which at least performs overlapped transmission on laminating films (11) and sheets (12) and thermal compression bonding; a control device (15) which controls the thermal compression bonding transmission device (10); an operation switch (16) which supplies power from a power supply (14) in operation. The thermal compression bonding transmission device (10) is provided with a plate-shaped heater (2) which comprises a PCT thermistor on at least one of compression transmission components (1) in pairs. The control device (15) is provided with the following components: a current detector (18) which detects the current value along with energization to the PCT thermistor in operation; and a preheating complement determination unit (15a) which determines whether the surface temperature of the compression bonding transmission component (1) reaches the preheating complement state with a temperature at which the laminating can be performed on condition that reduction change of the current value detected by the current detector (18) after peak of increase change reaches a preset value.

The mechanism designed on tray of optical disk drive directly is capable of stopping running optical disk effectively without influence on braking function caused by variation of outer cover or assembled position.

The invention relates to a mechanism related to hydraulic pressure safety in the field of injection molding machines, which is designed according to a requirement that a front door or a back door is opened independently or the front door and the back door are opened simultaneously to trigger to stop mold opening and closing actions of the injection molding machine. A specific control element is connected between a mechanical direction valve related to the front door and the rear door and a cartridge valve having a confirmation detection function according to certain specific serial-connecting and parallel-connecting requirements. The mold opening and closing actions of a mold opening and closing oil cylinder of an injection molding machine can be timely triggered, monitored and stopped under conditions that the front door or the back door is opened or the two safety doors are both opened, and the safety control requirement is achieved. Compared with the existing control systems, the hydraulic system for the relevant safety control of front and back doors of the injection molding machine can be installed conveniently, can be maintained simply, can timely and effectively stop the mold opening and closing actions and feed back a monitoring signal, and has high safety performance; after the hydraulic system is applied to national and regional injection molding machines with high safety requirement, the safety of the equipment is improved and the customer requirements are met effectively.

The invention discloses a parking guiding system and a guiding method thereof, wherein the guiding method comprises the following steps of: sending an image picked by an image sensor to an electronic controlling device by utilizing the combination of a display screen, the image sensor, a vehicle speed sensor and the electronic controlling device to judge a preset parking position, then obtaining the relative coordinates of a current position and the preset parking position through the picked image and a vehicle speed, estimating a parking starting position, and describing a concrete forward guide track from the vehicle current position to the preset parking position by passing through the parking starting position or the forward guide track from the current position to the parking starting position on the display screen according to a parking mode, so that a driver can refer to the display screen to easily, effectively and rapidly park the vehicle, and the occurrence of scraping and collision situations can also be effectively avoided.
