Description

Technical Field

[0001] The invention relates to the technical field of coal loading and unloading protection devices, and in particular to a personal safety protection device for a coal loading vehicle. Background Art

[0002] Coal, also known as coal, is the remains of ancient plants buried under the strata. It is a carbonized fossil mineral produced under the pressure and temperature conditions of the earth's crust that isolates the air. It is mainly mined by humans and used as fuel. During the coal transportation process, the coal needs to be loaded into the carriage first.

[0003] The pounding of coal by the coke oven coal loading car is carried out under the tamping coal tower of the coke oven. Because the location is windy and the temperature is low in winter, with the lowest temperature of minus 28℃, there is a fence around the tamping machine of the coal tower, which is 5cm higher than the railing on the top of the coal loading car. When there are people on the top platform of the coal loading car from the coal loading car to the tamping machine, safety accidents are prone to occur. At the same time, the tamping hammer may not be put away, and the tamping hammer may be damaged by the movement of the vehicle, resulting in a high incidence of equipment accidents. Therefore, a personal safety protection device for a coal loading car is urgently needed to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a personal safety protection device for a coal loading car in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A personal safety protection device for a coal-loading truck comprises a carriage, wherein a bearing platform is arranged on one side of an upper end of the carriage, an installation cavity is opened in the bearing platform, a bearing frame with a U-shaped structure is fixed in the installation cavity, two groups of infrared human body sensors are symmetrically installed at one end of the bearing frame, an explosion-proof glass plate is arranged on one side of the infrared human body sensor, an electric push rod is fixed in the middle part of the bearing frame, a CCD camera is installed on the movable part of the electric push rod, a screw is arranged between the inner walls of the bearing frame, a guide rod is installed on one side of the screw, a driving motor is connected to one end of the screw, a screw block is sleeved on the screw and the guide rod, and a brush is fixed on one side of the top of the screw block.

[0007] Furthermore, the bearing platform is formed on the carriage, and the mounting cavity is formed in the bearing platform.

[0008] By adopting the above technical solution, the carriage is used to load coal, the bearing platform is used to support tinkerers, and the mounting cavity provides a mounting position for the bearing frame.

[0009] Furthermore, a ladder is welded below one end of the bearing platform, and a reinforcement rod is welded between the ladder and the carriage.

[0010] By adopting the above technical solution, the ladder is convenient for tinkerers to get on and off the carriage, and the reinforcement rod can reinforce the ladder to improve its stability.

[0011] Furthermore, the support frame is fixed in the installation cavity by bolts, the infrared human body sensor is installed on one side of the ladder, and the explosion-proof glass plate is fixed to the detection end of the infrared human body sensor by a connecting column.

[0012] By adopting the above technical solution, when there is a tinkerer who passes through the ladder and is located on the carrying platform, the infrared human body sensor can detect it through the explosion-proof glass plate and transmit the detection signal to the cab. At this time, the vehicle cannot move under the coal tower to avoid causing personal injury. Only when the tinkerer comes down from the carrying platform, the infrared human body sensor detects it again to ensure that there is no tinkerer on the upper end of the carrying platform, and then the coal loading truck can move under the coal tower, realizing the interlocking with the walking of the coal loading truck, and effectively protecting the tinkerer.

[0013] Furthermore, the fixed part of the electric push rod is fixed in the supporting frame by bolts, and the CCD camera is fixed on the movable part of the electric push rod by screws.

[0014] By adopting the above technical solution, the electric push rod can drive the CCD camera to rise and fall, and then fix the tamping hammer when it is working. The tamping hammer is photographed by the CCD camera and the camera image is transmitted to the cab. The driver can ensure whether the tamping hammer is put away by observing the camera image, which can effectively solve the problem of the vehicle moving and damaging the tamping hammer when the tamping hammer is not put away, thereby reducing the occurrence of equipment accidents.

[0015] Furthermore, the screw rod is rotatably installed between the bearing frames, and the guide rod is welded between the bearing frames.

[0016] By adopting the above technical solution, the guide rod can guide the movement of the screw block.

[0017] Furthermore, the driving motor is fixed to a side wall of the supporting frame by means of bolts, and the output shaft of the driving motor is fixedly connected to one end of the screw rod.

[0018] By adopting the above technical solution, the driving motor provides power to the screw rod to make it rotate.

[0019] Furthermore, the screw block is mounted on the screw rod via threads, and the guide rod passes through the screw block.

[0020] By adopting the above technical solution, during the rotation of the screw rod, the screw block moves under the action of the thread and the guide rod.

[0021] Furthermore, the brush is fixed on the screw block by means of screws, and the brush is in contact with the CCD camera.

[0022] By adopting the above technical solution, when the CCD camera is in the installation cavity, the screw block drives the brush to move back and forth on the surface of the CCD camera to clean the coal dust attached to the surface, thereby ensuring the clarity of subsequent photography.

[0023] Furthermore, a sealing plate is fixed on the top of the installation cavity, a through cavity is opened at a position on the top of the sealing plate corresponding to the CCD camera, and a sealing cover with the same specification as the through cavity is fixed on the top of the CCD camera.

[0024] By adopting the above technical solution, the sealing plate can seal the installation cavity, the through cavity provides a lifting space for the CCD camera, and the sealing cover can seal the through cavity when the CCD camera is in the installation cavity, thereby protecting the CCD camera.

[0025] The specific working principle is: fix the bearing frame in the installation cavity and connect the electrical components inside it with the cab, and then install the sealing plate. In the process of loading coal through the carriage, when there is a tinkerer who passes through the ladder and is on the bearing platform, the infrared human body sensor can detect it through the explosion-proof glass plate and transmit the detection signal to the cab. At this time, the vehicle cannot move under the coal tower to avoid causing personal injury. Only when the tinkerer comes down from the bearing platform, the infrared human body sensor detects it again to ensure that there is no tinkerer on the upper end of the bearing platform, so that the coal loading car can move under the coal tower, realizing the interlocking with the walking of the coal loading car, which can effectively protect the tinkerer. When the coal is hit by the tinkering hammer, the electric The push rod drives the CCD camera to move through the through cavity to fix it. At this time, the CCD camera takes pictures of the tamping hammer and transmits the camera image to the cab. The driver can ensure whether the tamping hammer is put away by observing the camera image, which can effectively solve the problem of the tamping hammer being damaged by vehicle movement due to the tamping hammer not being put away, thereby reducing the occurrence of equipment accidents. When the tamping hammer is put away, the electric push rod drives the CCD camera to be in the installation cavity. At this time, the sealing cover seals the through cavity to protect the CCD camera. The driving motor drives the screw to rotate, so that the screw block drives the brush to move back and forth on the surface of the CCD camera under the action of the thread and the guide rod to clean the coal dust attached to its surface, thereby ensuring the clarity of its subsequent camera shooting.

[0026] The beneficial effects of the present invention are:

[0027] 1. By setting up an infrared human body sensor and an explosion-proof glass plate at the ladder, when the carriage moves under the coal tower, when there is a tinkerer on the load-bearing platform through the ladder, the infrared human body sensor can detect it through the explosion-proof glass plate and transmit the detection signal to the cab. At this time, the vehicle cannot move under the coal tower to avoid causing personal injury. Only when the tinkerer comes down from the load-bearing platform, the infrared human body sensor detects it again to ensure that there is no tinkerer on the upper end of the load-bearing platform, and then the coal loading car can move under the coal tower, realizing the interlocking with the coal loading car, which can effectively protect the tinkerer;

[0028] 2. By setting up an electric push rod and a CCD camera, when the coal is pounded by the tamping hammer, the electric push rod drives the CCD camera to move through the through cavity to fix it. At this time, the CCD camera takes a picture of the tamping hammer and transmits the camera image to the cab. The driver can ensure whether the tamping hammer is put away by observing the camera image, which can effectively solve the problem of the vehicle moving and damaging the tamping hammer due to the tamping hammer not being put away, thereby reducing the occurrence of equipment accidents.
