Detailed Description
The invention will now be further described with reference to the accompanying drawings.
Referring to fig. 1 and 2, the jaw spreader of the present invention comprises a gripping arm 101, a plate 102, a shutter 109, a connection structure 111, a hydraulic system and an electrical control system; the hydraulic system comprises an oil tank 104, a hydraulic cylinder piston 103 and a hydraulic cylinder, and the electric control system comprises a layer number selection switch 108, an electromagnetic valve 106 and a travel switch 107; the bottom of the hydraulic cylinder piston 103 is connected with the limiting plate 102, and the limiting plate 102 is positioned outside the hydraulic cylinder; the clamping arm 101 is connected with the lower part of the connecting structure 111, the upper end of the connecting structure 111 comprises a hoisting shaft 112, the upper part of the shutter 109 is connected with the hoisting shaft 112, the lower part of the shutter is connected with a hydraulic cylinder, when the hanger is lifted and the shutter is in an off state, the clamping arm 101 is closed to clamp a convection plate, and when the hanger falls and the shutter is in a closed state, the clamping arm 101 is released; the floor number selection switch 108 and the travel switch 107 are connected with the electromagnetic valve 106 and used for controlling the floor number position, and when the position of the floor number selection switch 108 is consistent with the position of the travel switch 107, the electromagnetic valve 106 is electrified, and the hydraulic cylinder piston 103 stops moving.
The parts of the clamp sling of the present invention are described further below.
The clamp arm 101 is used to clamp a convection plate. In this embodiment, there are two clamping arms 101, and each clamping arm 101 is formed in a semicircular arc shape so as to be matched with the arc surface of the convection plate. The opening and closing of the clamp arm 101 is controlled by the shutter 109 and the elevation of the clamp. When the shutter 109 is closed, the clamp arm 101 is opened, and when the shutter 109 is released and the clamp is raised, the clamp arm 101 is closed, thereby clamping the convection plate.
The hydraulic cylinder piston 103 is used for driving the limiting plate 102 positioned at the bottom of the hydraulic cylinder piston to move, and further control the position of the limiting plate 102.
The oil tank 104 is used for storing hydraulic oil. The hydraulic oil stored in the oil tank 104 can push the hydraulic cylinder piston 103 to move under the action of gravity.
The hydraulic cylinder comprises a hydraulic cylinder rod cavity 105 and a hydraulic cylinder rodless cavity 110, and the hydraulic cylinder rod cavity 105 and the hydraulic cylinder rodless cavity 110 are separated by a hydraulic cylinder piston 103. The rodless chamber 110, the rod chamber 105 and the oil tank 104 of the hydraulic cylinder are connected together through a two-position four-way valve. When the piston 103 of the hydraulic cylinder descends, the rodless cavity 110 starts to feed oil, the rod cavity 105 discharges oil, redundant oil enters the oil tank 104 due to the large volume difference between the two cavities, when the set position is reached, the electromagnetic valve is electrified, hydraulic oil stops flowing, and the oil in the rod cavity 105 and the oil tank 104 is in a static state and keeps the original state.
The solenoid valve 106 is used for controlling whether the hydraulic cylinder piston 103 moves or not. When the electromagnetic valve 106 is in a power-off state, the hydraulic cylinder piston 103 can move normally, and when the electromagnetic valve is in a power-on state, the hydraulic cylinder piston 103 is locked and stops moving. Whether the electromagnetic valve 106 is in the power-on state or not is controlled by the layer number selection switch 108 and the travel switch 107, and when the position of the layer number selection switch 108 is consistent with the position of the travel switch 107, the electromagnetic valve 106 is powered on, and the hydraulic cylinder piston 103 stops moving.
The travel switch 107 has a multi-step control switch, and the step number of the control switch is related to the number of convection plates which can be clamped at most. In this embodiment, the clamp spreader of the present invention can hold up to four convection plates, so the travel switch 107 has four-position control switches respectively corresponding to four positions of the limiting plate 102, and the four positions of the limiting plate 102 respectively correspond to four different situations, namely one, two, three, and four convection plates to be clamped. However, in other embodiments, if the number of convection plates that can be held is changed, the number of steps of the control switch of the stroke switch 107 needs to be changed correspondingly.
The above is a description of the clamp sling of the present invention. The operation of the spreader will be described with reference to specific examples.
In one working process, when a convection plate is selected to be hoisted, an operator selects the travel switch 7 to be on the first position, after the limit plate 102 descends to the lowest end (corresponding to the position of one convection plate), the electromagnetic valve 106 is electrified, the hydraulic system is closed, the clamping arm 101 falls down, the loose hooks at two ends are enlarged by the opening at the bottom of the clamping arm, and the convection plate is hoisted. When the number of convection plates to be hoisted changes, the buttons of the travel switches 7 change, and the positions of the wire laminates 102 are correspondingly adjusted, so that the convection plates with the corresponding number are hoisted.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and are not limited. Although the present invention has been described in detail with reference to the embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.
