The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1, an embodiment relates to an aerial work platform weight scaling experiment apparatus, which includes a support assembly 100 and a lifting assembly 200.
As shown in fig. 1 and 2, the lifting assembly 200 includes a beam 210 and a lifting member 220 connected to the beam 210, the support assembly 100 for supporting the beam 210, the lifting member 220 for placing the counterweight 400 on the aerial work platform 500; wherein, in the case that the counterweight 400 is placed on the aerial work platform 500 by the lifting member 220, the aerial work platform 500 can lift the counterweight 400 and the lifting assembly 200 together and separate the lifting assembly 200 from the support assembly 100 when being raised, and the aerial work platform 500 can drop the lifting assembly 200 onto the support assembly 100 so that the beam 210 is supported by the support assembly 100 when being lowered.
In the above-mentioned aloft work platform weight calibration experiment apparatus, when the supporting assembly 100 supports the cross beam 210, the lifting member 220 can lift the counterweight 400 and place the counterweight on the aloft work platform 500. With the counterweight 400 placed on the aerial work platform 500 by the jack 220, the aerial work platform 500 can lift the counterweight 400 and the lifting assembly 200 together when raised and separate the lifting assembly 200 from the support assembly 100, and the lifting assembly 200 can be lowered onto the support assembly 100 when the aerial work platform 500 is lowered so that the beam 210 is supported by the support assembly 100. Thus, the standard weight experiment of the aerial work platform 500 can be directly carried out without moving the hoisting assembly 200.
The aerial work platform 500 may be but not limited to a scissor-type lifting work platform, and in this embodiment, the design principle of the aerial work platform standard weight experiment apparatus is explained by taking the scissor-type lifting work platform as an example, and it cannot be understood that the aerial work platform standard weight experiment apparatus can only be applied to the scissor-type lifting work platform. The conventional scissor lift working platform is provided with a fence 510. As shown in fig. 2 and 4 and fig. 5, when the lifting member 220 places the counterweight 400 on the scissor lift work platform, the counterweight 400 is within the enclosure 510. When the scissor lift platform is lifted, the scissor lift platform jacks up the counterweight 400, and then when the fence 510 contacts the cross beam 210, the cross beam 210 and the lifting member 220 are jointly jacked up, the cross beam 210 is separated from the support assembly 100, and the cross beam 210 can fall onto the support assembly 100 when the scissor lift platform is lowered, so that the cross beam 210 is supported by the support assembly 100. Thus, when the scissor lift platform is lifted to the position where the fence 510 is in contact with the cross beam 210, the lifting part 220 enters the fence 510, so that the lifting part 220 is prevented from being pressed by the cross beam 210 when the scissor lift platform is lifted continuously.
As shown in fig. 6, further, if there is no rail 510 on the aerial work platform 500, a third limiting member 213 and a fourth limiting member 214 may be disposed on the beam 210, where the third limiting member 213 and the fourth limiting member 214 are spaced apart and disposed opposite to each other along the first direction; the hoisting member 220 is located between the third limiting member 213 and the fourth limiting member 214, and the third limiting member 213 and the fourth limiting member 214 can abut against the aerial work platform 500, so that an avoidance region is formed between the aerial work platform 500 and the cross beam 210. Thus, when the aerial work platform 500 is lifted to contact with the third limiting member 213 and the fourth limiting member 214, the lifting member 220 is located in the avoidance area, so that the lifting member 220 is prevented from being pressed by the cross beam 210 when the aerial work platform 500 is lifted up continuously.
As shown in fig. 1, in particular, the support assembly 100 includes a first support 110 and a second support 120, the first support 110 and the second support 120 are spaced apart and opposite to each other along a first direction, and the first support 110 and the second support 120 are respectively used for supporting two ends of the cross beam 210. An experiment area is formed between the first support member 110 and the second support member 120, the scissor-type lift platform is located in the experiment area during the experiment, and then the lifting member 220 is operated to lift the counterweight 400 to be placed on the scissor-type lift platform, so that the standard weight experiment can be performed. Thus, the first support member 110 and the second support member 120 are disposed to support the beam 210.
Optionally, the hoisting part 220 is a remote control electric hoist fixed in the middle of the beam 210, and the counterweight 400 is hung on a hook of the remote control electric hoist; specifically, the remote control electric hoist is hung on the cross beam 210. When the remote control electric hoist lifts the balance weight 400 and places the balance weight on the scissor type lifting working platform, a lifting rope of the remote control electric hoist should be kept in a loose state so as to ensure that the load borne by the scissor type lifting working platform during initial lifting is not less than the weight of the balance weight 400.
As shown in fig. 3, further, the first support 110 is provided with a first connecting portion 111 and a second connecting portion 112, the first connecting portion 111 and the second connecting portion 112 are arranged at an interval along the second direction, and a first limiting groove having a first receiving bottom wall 113 is formed between the first connecting portion 111 and the second connecting portion 112; a third lead connecting part and a fourth lead connecting part are arranged on the second support piece 120, the third lead connecting part and the fourth lead connecting part are arranged at intervals along the second direction, and a second limiting groove with a second bearing bottom wall is formed between the third lead connecting part and the fourth lead connecting part; when the supporting component 100 supports the hoisting component 200, two ends of the beam 210 are respectively located in the first limiting groove and the second limiting groove, and two ends of the beam 210 are respectively contacted with the first receiving bottom wall 113 and the second receiving bottom wall. Therefore, when the supporting component 100 is prevented from supporting the beam 210 by the constraint of the first limiting groove and the second limiting groove, the beam 210 is rocked along the second direction, so that the stability of the beam 210 is improved.
Wherein, the first direction is arranged perpendicular to the second direction.
As shown in fig. 3, further, the first limiting groove further has a first guiding sidewall 114 and a second guiding sidewall 115 located at two sides of the first receiving bottom wall 113, the first guiding sidewall 114 and the second guiding sidewall 115 are disposed at an interval along the second direction, and the distance between the first guiding sidewall 114 and the second guiding sidewall 115 gradually increases from the first receiving bottom wall 113 to the direction of the notch of the first limiting groove; the second limiting groove is provided with a third leading side wall and a fourth leading side wall which are positioned on two sides of the second bearing bottom wall, the third leading side wall and the fourth leading side wall are arranged at intervals along the second direction, and the distance between the third leading side wall and the fourth leading side wall is gradually increased from the second bearing bottom wall to the direction of the notch of the second limiting groove. After the scissor-type lifting working platform lifts the cross beam 210 to be separated from the support assembly 100, in the process of descending and recovering to the initial position, if the two ends of the cross beam 210 deviate in a certain range relative to the first receiving bottom wall 113 and the second receiving bottom wall, the first leading side wall 114 and the second leading side wall 115, and the third leading side wall and the fourth leading side wall can guide the cross beam 210 in the deviated position to the first receiving bottom wall 113 and the second receiving bottom wall, so that the stability of the cross beam 210 when being supported by the support assembly 100 is ensured.
It should be noted that, when the aerial work platform 500 is performing the standard weight experiment, the lifting member 220 only operates twice, and when the aerial work platform 500 operates for the first time, the lifting member 220 lifts the counterweight 400 to be placed on the aerial work platform 500, and at this time, the height of the aerial work platform 500 is smaller than the height of the counterweight 400 relative to the supporting surface of the aerial work platform 500; in the second run, it is the lifting member 220 that lifts the counterweight 400 off of the aerial work platform 500.
The initial position of the scissor lift platform refers to the position of the scissor lift platform relative to the support surface when the lifting member 220 is first operated.
As shown in fig. 1, in some embodiments, the aerial platform 500 weight testing apparatus further includes a position-finding element 300 and a controller electrically connected to the position-finding element 300, the lifting element 220 is communicatively connected to the controller, the position-finding element 300 is configured to detect whether the aerial platform 500 is at a predetermined testing position, and the controller is configured to control the lifting element 220 to place the weight 400 on the aerial platform 500 when the position-finding element 300 detects that the aerial platform 500 is at the predetermined testing position. Therefore, the aerial work platform standard weight experiment device can automatically lift the balance weight to ascend or descend.
The preset experiment position refers to a position of the first scissor-fork type lifting working platform under the counterweight 400.
The lifting member 220 is manipulated prior to the experiment to lift the counterweight 400 to a height at which the scissor lift work platform can move directly below the counterweight 400. When the first scissor lift platform moves to a position under the counterweight 400, and the position measuring element 300 detects that the first scissor lift platform is in place, the controller controls the lifting member 220 to lift the counterweight 400 to be placed on the first scissor lift platform. After the first scissor lift work platform is lifted and detected, the position detecting element 300 further detects that the aerial work platform is restored to the initial position, the controller communicates with the lifting element 220 to lift the counterweight 400 and leave the first scissor lift work platform, and then the first scissor lift work platform is manually operated to leave the experimental position. When testing the second table and cutting fork type lifting working platform, the experiment process of the first table and cutting fork type lifting working platform is repeated. So, when many scissors fork lift work platform need be tested, after adjusting the initial height of counter weight 400 before first scissors fork lift work platform experiment, the scissors fork lift work platform that carries out the experiment at the back only needs to remove the position that position finding component 300 detected, and the hoisting member 220 just can be automatic lifts by crane counter weight 400 and place or lift by crane and leave on scissors fork lift work platform to improve experimental efficiency.
Optionally, the position detecting element 300 is a correlation photoelectric sensor; the controller is a single chip microcomputer. Wherein, the communication connection is wireless connection, and is specific, and wireless connection is the bluetooth connection.
As shown in fig. 1, in some embodiments, a first limiting member 211 and a second limiting member 212 are disposed on the cross beam 210, and the first limiting member 211 and the second limiting member 212 are spaced apart from each other along a first direction and are disposed opposite to each other; the first limiting member 211 and the second limiting member 212 cooperate to form a clamping structure for clamping the aerial work platform 500. When the rail 510 of the scissor lift platform contacts the lifting assembly 200, the rail 510 enters between the first retaining member 211 and the second retaining member 212, and then the cross beam 210 is lifted. In this manner, rocking in a first direction relative to rail 510 when beam 210 is separated from support assembly 100 is avoided.
Further, a first magnetic member is disposed on the first limiting member 211, a second magnetic member is disposed on the second limiting member 212, and a first magnetic attraction portion magnetically engaged with the first magnetic member and a second magnetic attraction portion magnetically engaged with the second magnetic member are disposed on the counterweight 400. Specifically, the first magnetic member is located on a side of the first limiting member 211 close to the second limiting member 212, and the second magnetic member is located on a side of the second limiting member 212 close to the first limiting member 211. The first magnetic attraction part and the second magnetic attraction part are located on two sides of the fence 510 of the aerial work platform 500, which are opposite to each other along the first direction. When the fence 510 of the aerial work platform 500 contacts the first limiting member 211 and the second limiting member 212, the first magnetic member and the second magnetic member are magnetically attracted to the first magnetic attraction portion and the second magnetic attraction portion, so that the scissor-type lifting work platform can accurately enter between the first limiting member 211 and the second limiting member 212. Optionally, the magnetic member may be a magnet or a magnetite; the magnetic attraction piece can be made of iron, nickel, cobalt and other magnetism attracting metals.
In some embodiments, the cross beam 210 may further include a fifth limiting member and a sixth limiting member, and the fifth limiting member and the sixth limiting member are spaced apart from each other along the second direction and are disposed opposite to each other; a clamping structure for clamping the aerial work platform 500 is formed between the fifth limiting piece and the sixth limiting piece. When the rail 510 of the scissor lift platform contacts the lifting assembly 200, the rail 510 enters between the first limiting member 211 and the second limiting member 212, and also enters between the third limiting member 213 and the fourth limiting member 214, and then the cross beam 210 is lifted. In this manner, rocking in the first and second directions relative to the scissor lift work platform when the cross beam 210 is disengaged from the support assembly 100 is avoided.
In some embodiments, the first support 110 is provided with a neutral connection at one end for supporting the beam 210, and the second support 120 is provided with a live connection at one end for supporting the beam 210; a first conductive piece and a second conductive piece are respectively arranged at two ends of the beam 210, and the first conductive piece and the second conductive piece are respectively in conductive connection with the positive electrode and the negative electrode of the hoisting piece 220; when the supporting member 100 supports the beam 210, the first conductive member is electrically contacted with the live wire terminal, and the second conductive member is electrically contacted with the neutral wire terminal. The lifting member 220 is connected to the circuit when the beam 210 is in contact with the support assembly 100, so the lifting member 220 can be normally operated only when the support assembly 100 supports the beam 210. Therefore, the lifting weight 400 is prevented from being lifted due to the failure of the controller in the lifting process of the lifting member 220, and the situation that the power line is broken in the lifting process when the lifting member 220 uses the power line access circuit is also avoided.
As shown in fig. 7, an embodiment relates to an experimental method for weighting an aerial work platform 500, in which the above experimental apparatus for the aerial work platform 500 is applied, and the experimental method for weighting the aerial work platform 500 includes: step S1, the lifting member 220 is operated to suspend the counterweight 400 on the aerial work platform 500; step S2, the aerial work platform 500 is controlled to be lifted to a first preset height, so that the counterweight 400 and the lifting assembly 200 are lifted by the aerial work platform 500, wherein the lifting assembly 200 is separated from the supporting assembly 100 when the aerial work platform 500 is lifted to the first preset height; step S3, controlling the aerial work platform 500 to descend to a second preset height, wherein the beam 210 contacts the supporting component 100 and is supported by the supporting component 100 when the aerial work platform 500 descends to the second preset height; step S4, repeating step S2 and step S3 for the preset number of tests; in step S5, the lifting member 220 is activated to lift the counterweight 400, so that the counterweight 400 is separated from the aerial work platform 500, thereby completing the test. Thus, through the above experimental method, the standard weight experiment of the aerial work platform 500 can be completed quickly without moving the lifting piece 220.
Specifically, in this embodiment, the first preset height is a maximum lifting height of the scissor-type lifting working platform. The second preset height is the minimum height when the scissor-type lifting working platform contracts, and the preset inspection times are at least twice.
It should be noted that, before the experiment, the height of the counterweight 400 relative to the supporting surface of the scissor lift platform is higher than the height of the scissor lift platform when the scissor lift platform is retracted. So that the scissor type lifting working platform can be moved to the position right below the standard weight for carrying out experiments. After the test of the first scissor-type lifting working platform is completed, the first scissor-type lifting working platform is operated to move away from the experimental area, and when the test of the second scissor-type lifting working platform is performed, the height of the balance weight 400 relative to the supporting surface of the scissor-type lifting working platform does not need to be adjusted, and the test method of the aerial work platform 500 can be directly performed.
