Description

Technical Field

[0001] The present invention belongs to the technical field of gantry crane safety equipment, and in particular relates to a side anti-collision safety device for a gantry crane. Background Art

[0002] The gantry crane is a deformation of the bridge crane, also known as the gantry crane. It has the characteristics of high site utilization rate, large operation range, wide adaptability, strong versatility, etc., and is a commonly used equipment for hoisting large heavy objects. Although at present, induction alarm devices are installed on the outriggers of the gantry crane, which can immediately issue an alarm and automatically stop moving when an obstacle is sensed to avoid collisions, the induction device can usually only sense obstacles directly in front, and cannot sense side obstacles. Since there are often equipment such as engines protruding from the outriggers, if there are operators on the side of the outriggers, the protruding engine components are likely to collide with the operators, posing a great safety hazard. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a side anti-collision safety device for a gantry crane.

[0004] To achieve the above object, the technical solution of the present invention is realized as follows:

[0005] A side anti-collision safety device for a gantry crane includes a main frame body. The main frame body includes a cross arm, and two groups of adjustment mechanisms are arranged in parallel on the cross arm, and the two groups of adjustment mechanisms are on the same side of the cross arm. An L-shaped adjustment frame is provided at the front end of the cross arm. The adjustment frame includes a vertical connecting body and a horizontal mounting body; both the mounting body and the connecting body adopt telescopic structures; the connecting body is fixed to the cross arm, and an induction baffle is provided at its free end; the adjustment mechanism includes a connecting rod and a fixed rod sleeved on the connecting rod. The fixed rod and the connecting rod are in sliding fit. The connecting rod is fixed to the cross arm. A rubber plug is filled in the inner cavity of the fixed rod at the end far from the cross arm, and a limit baffle is provided at the end of the connecting rod close to the cross arm.

[0006] Further, the connecting rod is welded and fixed to the cross arm.

[0007] Further, a rubber pad or a sponge pad is provided on the side of the cross arm different from the adjustment mechanism.

[0008] Further, the cross arm, the connecting rod, and the fixed rod are all made of square steel pipes.

[0009] Further, the mounting body includes an inner mounting rod body and an outer mounting rod body sleeved outside the inner mounting rod body, and the two are fixed by a locking screw.

[0010] Further, the connecting body includes an inner connecting rod body and an outer connecting member rod body sleeved outside the inner connecting rod body, and the two are fixed by a locking screw.

[0011] Further, the induction baffle is welded and fixed to the connecting body.

[0012] Further, the induction baffle and the adjustment mechanism are arranged on the same side of the main frame body.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The anti-collision safety device provided by the present invention is installed on the protruding structure on the outer side of the leg of the gantry crane. When the gantry crane is working, if there are obstacles or operators on the side of the leg, it will come into contact with the cross arm. As the adjustment mechanism is compressed and shortened, the distance between the induction baffle and the induction alarm device at the leg changes. After the induction baffle is sensed by the induction alarm device at the leg, an alarm is issued, and the movement of the gantry crane is automatically stopped, ensuring that the main structure of the gantry crane does not collide with obstacles and eliminating the potential safety hazard of collision on the side structure of the leg.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific circumstances.

[0023] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0024] A side anti-collision safety device for a gantry crane, as Figures 1 to 4 shown, includes a main frame body 1. The main frame body includes a cross arm 3. Two sets of adjustment mechanisms are arranged in parallel on the cross arm, and the two sets of adjustment mechanisms are on the same side of the cross arm. An L-shaped adjustment frame 4 is provided at the front end of the cross arm. The adjustment frame includes a vertical connecting body 5 and a horizontal mounting body 6; both the mounting body and the connecting body adopt a telescopic structure; the connecting body is fixed to the cross arm, and an induction baffle 7 is provided at its free end; the adjustment mechanism includes a connecting rod 8 and a fixed rod 9 sleeved on the connecting rod. The fixed rod and the connecting rod are in sliding fit. The connecting rod is fixed to the cross arm. A rubber plug is filled in the inner cavity of the fixed rod at the end far from the cross arm. Since a rubber plug is provided at the end of the fixed rod, during the process of the connecting rod retracting into the fixed rod, even when the connecting rod reaches the limit position, it will not cause damage to the end of the fixed rod, and the rubber plug plays a buffering role for the connecting rod. A limit baffle 10 is provided at the end of the connecting rod close to the cross arm. By adjusting the connecting body and the mounting body respectively, the induction baffle can be aligned with the induction alarm device on the gantry crane leg.

[0025] This device is installed on the protruding structural member outside the leg of the gantry crane. For example, the installation body is welded and fixed on the motor mounting seat 12 outside the leg 2 of the gantry crane. When the gantry crane is working, once the cross arm touches an obstacle or an operator, the adjustment mechanism will be compressed and shortened (the connecting rod will be pressed into the fixed rod or partially pressed into the fixed rod). As the induction baffle on the main frame body (adjustment frame) approaches the sensor 11 on the leg of the gantry crane, the obstacle information on the side of the leg can be fed back, which can solve the problem that the induction alarm device on the leg of the gantry crane can only sense obstacles in the front and cannot sense and identify side obstacles. Applying this device can identify side obstacles at the leg in advance, give an alarm, and at the same time control the equipment to stop moving, which can strengthen the safety protection of the gantry crane.

[0026] Generally, the connecting rod is welded and fixed to the cross arm. The cross arm, connecting rod, and fixed rod are all made of square steel pipes. A rubber pad or sponge pad is provided on the side of the cross arm different from the adjustment mechanism to avoid damage to the object or operator when touching the object or operator. The induction baffle is welded and fixed to the connecting body. The induction baffle and the adjustment mechanism are arranged on the same side of the main frame body.

[0027] For example, the installation body includes an inner installation rod body and an outer installation rod body sleeved outside the inner installation rod body, and the two are fixed by locking screws. The connecting body includes an inner connecting rod body and an outer connecting member rod body sleeved outside the inner connecting rod body, and the two are fixed by locking screws. Of course, those skilled in the art can also adopt other telescopic structural forms, as long as the installation body and the connecting body can be telescopically adjusted and fixed at an appropriate length as required. By adjusting the lengths of the installation body and the connecting body, the induction baffle is aligned with the induction alarm device on the leg of the gantry crane, ensuring that the induction baffle can move into the alarm range of the induction alarm device on the leg of the gantry crane, effectively solving the problem that side obstacles of the leg cannot be sensed by the induction alarm device.

[0028] The anti-collision safety device provided by this invention is installed on the protruding structure outside the leg of the gantry crane. When there are obstacles or operators on the side of the leg during the operation of the gantry crane, it will come into contact with the cross arm. As the adjustment mechanism is compressed and shortened, the distance between the induction baffle and the induction alarm device at the leg changes. After the induction baffle is sensed by the induction alarm device at the leg, an alarm is issued and the movement of the gantry crane is automatically stopped, ensuring that the main structure of the gantry crane does not collide with the obstacle, eliminating the potential safety hazard of collision of the side structure of the leg. Moreover, the device is simple and practical, easy to manufacture and install, and can be recycled, having good economic and safety benefits.

[0029] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
