Description

Technical Field

[0001] The invention relates to the technical field of auxiliary transportation of mining monorail cranes, which belongs to the scope of safe transportation of mining monorail crane locomotives, and specifically refers to a lifting beam that can rotate and translate. Background Art

[0002] As an auxiliary transportation equipment for coal mines, monorail crane locomotives have the advantages of strong safety, strong driving force, strong adaptability, small space occupation, and high transportation efficiency. They are widely used in narrow spaces such as tunnels and mines, and are auxiliary transportation equipment suitable for most coal mines in my country. Monorail crane locomotives (hereinafter referred to as locomotives) are powered by explosion-proof diesel engines or batteries. The locomotives can move along the track 6 suspended above the tunnel or mine. The materials are suspended by the lifting beam connected to the locomotive. The lifting beam moves along the track 6 under the traction of the locomotive to lift the materials.

[0003] The existing lifting beam is limited by the track and can only transport objects in a straight line forward and backward along the length direction of the track 6. When loading and unloading materials such as unit brackets and transformers, the materials are placed on the ground, and personnel need to use cylinders, wire ropes, etc. to move the materials left and right again to the placement or lifting position. In this way, the materials placed on the ground need to be moved in other ways before they can be loaded and unloaded through the lifting beam. The process is cumbersome, and accidents are very likely to occur during all translation processes, posing safety hazards. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a lifting beam which can move left and right to transport materials after moving forward and backward along a track, thereby achieving rapid and safe transportation of underground materials and further improving the efficiency of transportation and placement.

[0005] The present invention is achieved through the following technical scheme: a lifting beam that can rotate and translate, an upper beam frame that slides back and forth along a track, and a lifting hoist. A revolving beam frame is installed on the upper beam frame, and a load-bearing beam frame is connected to the revolving beam frame so as to slide left and right. The revolving beam frame is installed with a first driver that drives the load-bearing beam frame to slide, and the lifting hoist is installed on the load-bearing beam frame.

[0006] This solution lifts the material through the lifting hoist, moves the upper beam frame along the track in the front and rear direction, and moves the material left and right by sliding the load-bearing beam frame along the rotating beam frame, thereby realizing fast and safe transportation of underground materials and improving the efficiency of transportation and placement.

[0007] As an optimization, the rotating beam frame is horizontally rotatably connected with the upper beam frame. In this optimization solution, the rotating beam frame and the upper beam frame rotate horizontally, and the material movement angle and direction can be adjusted arbitrarily, thereby improving the convenience of use.

[0008] As an optimization, the hoisting hoist is horizontally rotatably connected to the load-bearing beam frame. In this optimization solution, the hoisting hoist and the load-bearing beam frame rotate horizontally, and the placement angle and direction of the material can be adjusted arbitrarily, thereby improving the convenience of use.

[0009] As an optimization, the rotating beam frame is provided with a left leg and a right leg for supporting the rotating beam frame. This optimization scheme supports the rotating beam frame by the left leg and the right leg, thereby improving the stability and safety of the lifting beam when loading and unloading materials.

[0010] As an optimization, the left leg and the right leg are retractable. This optimization solution enables the left leg and the right leg to be suitable for different installation heights and can provide support.

[0011] As an optimization, the left leg is connected to the slewing beam through a transverse swing arm, one end of the swing arm is connected to the left leg, and the other end of the swing arm is hinged to the slewing beam, and a second driver for driving the swing arm to swing horizontally is installed on the slewing beam. This optimization scheme allows the front leg to be locked at any angle within a range through the horizontal swing of the swing arm, and the horizontal extension angle of the front leg can be independently controlled, thereby improving environmental adaptability.

[0012] As an optimization, one end of the left leg is vertically rotatably connected to the end of the swing arm, and a third driver for driving the left leg to rotate is installed on the swing arm. This optimization solution enables the left leg to be rotated to a horizontal state and retracted when transporting materials, avoiding collision with objects and facilitating rapid conversion of loading and unloading-transportation working states.

[0013] As an optimization, one end of the right leg is vertically connected to the slewing beam, and a fourth driver for driving the right leg to rotate is installed on the slewing beam. This optimization solution enables the right leg to be rotated to a horizontal state and retracted when transporting materials, avoiding collision with objects and facilitating rapid conversion of loading and unloading-transportation working states.

[0014] As an optimization, the left leg is hingedly mounted with a left leg seat at the other end, and the right leg is hingedly mounted with a right leg seat at the other end. In this optimization scheme, the left leg seat and the right leg seat can be deflected and moved within a certain range to adapt to the uneven top and bottom plates at the application site.

[0015] As an optimization, the first driver includes a nut-screw pair and a motor, one end of the screw of the nut-screw pair is rotatably connected to the rotating beam frame, the other end of the screw passes through the load-bearing beam frame, the nut of the nut-screw pair is fixedly connected to the load-bearing beam frame, the motor is fixedly installed on the rotating beam frame and the motor output end is fixedly connected to the end of the screw; the second driver is a telescopic cylinder, and the third driver and the fourth driver are rotary drives. In this optimization solution, the first driver drives the sliding of the load-bearing beam frame through the nut-screw pair driven by the motor.

[0016] The beneficial effects of the present invention are as follows: the upper beam frame moves forward and backward along the track, the moving direction of the material can be arbitrarily adjusted by the rotating beam frame, and the material is driven to move in the left and right directions by the sliding of the load-bearing beam frame, so as to realize the rapid and safe transportation of underground materials and improve the efficiency of transportation and placement;

[0017] When loading and unloading materials, the left and right outriggers effectively support the slewing beam frame to avoid the center of gravity shifting when moving materials left and right, which causes the lifting beam to tilt and shake, thus ensuring the stability and safety of the lifting beam when loading and unloading materials;

[0018] The left outrigger and the right outrigger can be rotated arbitrarily in the vertical direction. The supporting positions of the left outrigger and the right outrigger can be adjusted accordingly according to the center of gravity offset state when the material is moved. The left outrigger and the right outrigger can be rotated and folded during transportation, realizing the rapid conversion of loading and unloading-transportation working states, which greatly improves the convenience of use.

A revolving beam frame 2 is mounted on the upper beam frame 1, and the revolving beam frame 2 is connected to the upper beam frame 1 in a horizontally rotatable manner.

[0028] like Figure 1 , 3 As shown, the upper beam frame 1 of this embodiment is a frame structure, the track 6 is an H-shaped steel extending forward and backward, and the front and rear ends of the upper beam frame 1 slide forward and backward along the H-shaped steel groove through two load trolleys 61. This is an existing conventional technology and will not be described in detail here.

[0029] like Figure 1 , 3 As shown, the slewing beam 2 of this embodiment is rotatably connected to the bottom of the upper beam 1 through a slewing support mechanism 7, as shown in FIG. Figure 5 As shown, the slewing bearing mechanism 7 includes an upper fixed plate 71 and a lower fixed plate 72, which are distributed up and down, and a slewing bearing 73. The upper fixed plate 71 is fixed to the outer ring of the slewing bearing 73, and the lower fixed plate 72 is fixed to the inner ring of the slewing bearing 73. The upper fixed plate 71 is fixed to the upper beam frame 1, and the lower fixed plate 72 is fixed to the slewing beam frame 2.

[0030] The rotating beam frame 2 is connected to the load-bearing beam frame 3 in a left-right sliding manner, and the rotating beam frame 2 is equipped with a first driver 21 that drives the load-bearing beam frame 3 to translate and slide.

[0031] like Figure 1 , 4 As shown, the revolving beam 2 and the load-bearing beam 3 of this embodiment are both rectangular frame structures formed by welding four channel steels. Rollers 32 are hinged on the left and right sides of the load-bearing beam 3, and the load-bearing beam 3 slides in the slide groove 33 of the revolving beam channel steel through the rollers 32.

[0033] The first driver 21 includes but is not limited to a nut-screw pair structure driven by a motor, a gear rack structure, a worm gear structure, a chain sprocket structure, or directly uses a telescopic cylinder to drive, which can achieve the same function. The above structures are all existing commonly used linear drive structures and will not be elaborated here.

[0034] The lifting hoist 31 is installed on the load-bearing beam frame 3 , and the lifting hoist 31 is connected to the load-bearing beam frame 3 in a horizontally rotatable manner.

[0035] like Figure 1 , 2As shown, in this embodiment, two lifting hoists 31 are provided, and the lifting hoists 31 are also rotatably connected to the bottom of the load-bearing beam frame 3 through the slewing support mechanism 7. The upper fixed plate 71 is fixedly connected to the bottom of the load-bearing beam frame 3, and the two lifting hoists 31 are fixedly installed on the lower fixed plate 72.

[0036] In the present application, the upper beam frame 1 and the slewing beam frame 2, the bearing beam frame 3 and the hoisting hoist 31 can be driven to rotate by a motor, the motor is fixedly mounted on the upper fixed plate 71 of the slewing support mechanism 7, and the output end of the motor is fixedly connected to the inner ring of the slewing support 73. Alternatively, the upper beam frame 1 and the slewing beam frame 2, the bearing beam frame 3 and the hoisting hoist 31 can be rotatably connected by a slewing drive, and the rotation effect can be achieved, further saving manpower.

[0037] like Figure 1 As shown, the left and right sides of the rotating beam frame 2 are provided with a left leg 4 and a right leg 5 supporting the rotating beam frame, and the left leg 4 and the right leg 5 are provided with two, and the left leg 4 and the right leg 5 are telescopically arranged. The left leg and the right leg in this embodiment are hydraulic cylinders.

[0038] The left leg 4 is connected to the rotating beam 2 via a transverse swing arm 44, one end of the swing arm 44 is connected to the left leg 4, and the other end of the swing arm 44 is hinged to the rotating beam 2. A second driver 41 is installed on the rotating beam 2 to drive the swing arm 44 to swing horizontally.

[0039] like Figure 1 As shown, in this embodiment, the two left legs 4 are respectively mounted on the front and rear side walls of the left end of the rotating beam 2 through the swing arm 44, and the second driver 41 is a telescopic cylinder, and the two ends of the telescopic cylinder are respectively hinged to the rotating beam 2 and the swing arm 44.

[0040] like Figure 1 As shown, one end of the left leg 4 is vertically rotatably connected to the end of a swing arm 44, and a third driver 42 for driving the left leg 4 to rotate is installed on the swing arm 44. A left leg seat 43 is hingedly installed on the other end of the left leg 4. In this embodiment, the left leg seat 43 is connected to the left leg 4 by a ball joint.

[0041] The third driver 42 in this embodiment is a rotary driver, the fixed end of the rotary driver is fixedly connected to the outer wall of the swing arm 44, and the end of the left leg 4 is fixedly connected to the rotating end of the rotary driver through a mounting seat. Figure 3 As shown, when the two left legs 4 rotate to a horizontal state, they are driven by the swing arm 44 to fit respectively on the front and rear side walls of the rotating beam frame 2. In this embodiment, the front and rear side walls of the rotating beam frame 2 are respectively fixed with limit frames 8 for limiting the swing arms. During towing and transportation, the lifting beam supports the swing arms through the limit frames to prevent the swing arms from falling.

[0042] like Figure 1As shown, one end of the right leg 5 is vertically rotatably connected to the rotating beam 2, and a fourth driver 51 for driving the right leg 5 to rotate is installed on the rotating beam 2. A right leg seat 52 is hingedly installed on the other end of the right leg 5. In this embodiment, the right leg seat 52 is connected to the right leg 5 by a ball joint.

Figure 2 As shown, counterweight blocks 9 are fixedly connected to the front and rear side walls of the right end of the rotating beam frame 2, respectively. Two counterweight blocks are provided to compensate for the left and right mass imbalance of the rotating beam frame 2 caused by the eccentric arrangement of the rotating support mechanism 7, optimize the stress state of the rotating support mechanism 7, and reduce the inclination of the lifting beam caused by the rotation of the rotating beam frame.

[0044] It should be noted that the motor of this embodiment can achieve the above functions in the form of hydraulic, pneumatic, electric drive, etc., and the hydraulic cylinder and telescopic cylinder can be replaced by pneumatic, electro-hydraulic push rods, electric cylinders, etc. to achieve the same functions without affecting the use of the equipment.

[0045] Working principle: When in use, the upper beam frame 1 of the lifting beam is connected to the locomotive on the track 6, and the initial state of the lifting beam is as follows: Figure 3 As shown, the lifting beam is in loading and unloading state. Figure 1 As shown. When hoisting materials located on the side of the track, the slewing beam 2 rotates to the direction of the materials, the second driver 41 drives the swing arm 44 to rotate and extend in the horizontal direction, and the third driver 42 drives the left leg 4 to rotate to the vertical downward direction, and the left leg 4 extends downward to contact the ground. The fourth driver 51 drives the right leg 5 to rotate to the vertical upward direction, and the right leg 5 extends upward to contact the top plate to prevent the other end from tilting upward due to the outward shift of the center of gravity of the material at one end of the slewing beam 2. The first driver 21 drives the load-bearing beam 3 to slide in the direction of the left leg 4 to just above the material. After the lifting hoist 31 lifts the material, the load-bearing beam 3 slides to just below the upper beam 1 to keep the center of gravity balanced. After retracting the left leg 4 and the right leg 5, the locomotive drives the lifting beam to move along the track to the designated position to unload the material.

[0046] When unloading materials, the slewing beam 2 rotates to the unloading position, the left leg 4 and the right leg 5 are extended for support, the bearing beam 3 slides toward the left leg 4 to the top of the unloading position, and the hoisting hoist 31 rotates the material to the required angle to unload the material. After the material is placed, the bearing beam 3, the left leg 4, the right leg 5, the slewing beam 2 are recovered in the reverse order. Figure 3 state.
