As shown in fig. 1, an embodiment relates to a device for testing the weight of a platform for aloft work, which comprises a supporting 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 coupled to the beam 210, the support assembly 100 for supporting the beam 210, and the lifting member 220 for placing the counterweight 400 on the aerial work platform 500; wherein, in the case that the weight 400 is placed on the aerial work platform 500 by the lifting member 220, the aerial work platform 500 can jack up the weight 400 together with the lifting assembly 200 when being lifted up and separate the lifting assembly 200 from the supporting assembly 100, and the aerial work platform 500 can drop the lifting assembly 200 onto the supporting assembly 100 when being lowered down so that the cross beam 210 is supported by the supporting assembly 100.
In the aerial work platform scale weight experiment device, when the supporting assembly 100 supports the cross beam 210, the lifting member 220 can lift and place the counterweight 400 on the aerial work platform 500. In the case where the hoist 220 places the weight 400 on the aerial work platform 500, the aerial work platform 500 can jack up the weight 400 together with the hoist assembly 200 when lifted and separate the hoist assembly 200 from the support assembly 100, and the aerial work platform 500 can drop the hoist assembly 200 onto the support assembly 100 when lowered so that the cross beam 210 is supported by the support assembly 100. Thus, the standard weight experiment of the aerial work platform 500 can be directly performed without moving the lifting assembly 200.
The aerial work platform 500 may be, but is not limited to, a scissor fork type lifting work platform, and the design principle of the aerial work platform scale experiment device is explained by taking the scissor fork type lifting work platform as an example in this embodiment, and it cannot be understood that the aerial work platform scale experiment device can only be applied to the scissor fork type lifting work platform. The conventional scissor lift platforms are provided with a rail 510. As shown in fig. 2 and 4 and fig. 5, when the lifting member 220 places the weight 400 on the scissor lift work platform, the weight 400 is within the rail 510. When the scissor lift platform is lifted, the scissor lift platform will jack up the counterweight 400 first, then jack up the beam 210 and the lifting member 220 together when the rail 510 contacts the beam 210, and separate the beam 210 from the support assembly 100, and the scissor lift platform can drop onto the support assembly 100 when it is lowered, so that the beam 210 is supported by the support assembly 100. In this manner, when the scissor lift platform is raised to the point where rail 510 contacts beam 210, lifting member 220 enters rail 510, thereby avoiding lifting member 220 from being capped by beam 210 as the scissor lift platform continues to lift.
As shown in fig. 6, further, if the aerial platform 500 does not have the rail 510, the beam 210 may be provided with a third limiting member 213 and a fourth limiting member 214, and 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 lifting 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 platform 500, so that an avoidance area is formed between the aerial platform 500 and the beam 210. In this manner, when the aerial work platform 500 is raised to contact the third stopper 213 and the fourth stopper 214, the lifting member 220 is located in the avoidance area, thereby avoiding the lifting member 220 from being capped by the cross beam 210 when the aerial work platform 500 continues to lift.
As shown in fig. 1, in particular, the support assembly 100 includes a first support 110 and a second support 120, where the first support 110 and the second support 120 are spaced apart and disposed 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 beam 210. An experiment area is formed between the first supporting member 110 and the second supporting member 120, the scissor fork type lifting work platform is located in the experiment area during the experiment, and then the lifting member 220 is controlled to lift and place the counterweight 400 on the scissor fork type lifting work platform, so that the weight calibration experiment can be performed. In this way, the first support member 110 and the second support member 120 are disposed, so as to support the beam 210.
Optionally, the lifting member 220 is a remote control electric hoist, the remote control electric hoist is 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 beam 210. When the remote control electric hoist lifts the counterweight 400 on the scissor lift working platform, the lifting rope of the remote control electric hoist should be kept in a loose state so as to ensure that the load born by the scissor lift working platform during primary lifting is not less than the weight of the counterweight 400.
As shown in fig. 3, further, the first support 110 is provided with a first receiving portion 111 and a second receiving portion 112, the first receiving portion 111 and the second receiving portion 112 are spaced along the second direction, and a first limiting groove with a first receiving bottom wall 113 is formed between the first receiving portion 111 and the second receiving portion 112; the second supporting piece 120 is provided with a third connecting and guiding part and a fourth connecting and guiding part, the third connecting and guiding part and the fourth connecting and guiding part are arranged at intervals along the second direction, and a second limiting groove with a second supporting bottom wall is formed between the third connecting and guiding part and the fourth connecting and guiding part; when the supporting assembly 100 supports the lifting assembly 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 supporting bottom wall 113 and the second supporting bottom wall. In this way, through the constraint of the first limiting groove and the second limiting groove, when the beam 210 is supported by the support assembly 100, the beam 210 is prevented from swinging along the second direction, so that the stability of the beam 210 is improved.
Wherein the first direction is perpendicular to the second direction.
As shown in fig. 3, 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 spaced 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 notch of the first limiting groove; the second limiting groove is provided with a third guide side wall and a fourth guide side wall which are positioned at two sides of the second bearing bottom wall, the third guide side wall and the fourth guide side wall are arranged at intervals along the second direction, and the distance between the third guide side wall and the fourth guide side wall is gradually increased from the second bearing bottom wall to the notch of the second limiting groove. After the cross beam 210 is lifted to be separated from the supporting component 100 by the scissor type lifting working platform, in the process of descending and restoring to the initial position, if the two ends of the cross beam 210 deviate to a certain extent relative to the first supporting bottom wall 113 and the second supporting bottom wall, the first guiding side wall 114, the second guiding side wall 115, the third guiding side wall and the fourth guiding side wall can guide the cross beam 210 at the deviating position to the first supporting bottom wall 113 and the second supporting bottom wall, so that the stability of the cross beam 210 when supported by the supporting component 100 is ensured.
It should be noted that, when the aerial platform 500 performs the standard weight experiment, the crane 220 only runs twice, and when the crane 220 runs for the first time, the counterweight 400 is lifted and placed on the aerial platform 500 by the crane 220, and at this time, the height of the aerial platform 500 is smaller than the height of the counterweight 400 relative to the supporting surface of the aerial platform 500; the second time that is to run, the lifting member 220 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 work platform 500 scale weight experiment device further includes a positioning element 300 and a controller electrically connected to the positioning element 300, where the crane 220 is communicatively connected to the controller, and the positioning element 300 is configured to determine whether the aerial work platform 500 is at a preset experiment position, and the controller is configured to control the crane 220 to place the counterweight 400 on the aerial work platform 500 when the positioning element 300 detects that the aerial work platform 500 is at the preset experiment position. Therefore, the aerial working platform standard weight experimental device can automatically lift the counterweight to rise or fall.
The preset experiment position refers to a position when the first scissor fork type lifting work platform is located right below the counterweight 400.
The crane 220 is manipulated prior to the experiment to raise the counterweight 400 to a height where the scissor lift work platform can move directly under the counterweight 400. When the first scissor lift platform moves directly under the counterweight 400, the positioning element 300 detects that the first scissor lift platform is in place, and the controller communicates to control the crane 220 to hoist and place the counterweight 400 on the first scissor lift platform. After the first scissor lift platform is lifted and detected, the positioning element 300 detects that the aerial work platform is restored to the initial position, the controller communicates to control the lifting member 220 to lift the counterweight 400 and leave the first scissor lift platform, and then manually operates the first scissor lift platform to leave the experimental position. When the second scissor fork type lifting work platform is tested, the experimental flow of the first scissor fork type lifting work platform is repeated. So, when needing to test many scissors fork lift work platform, after adjusting the initial height of first scissors fork lift work platform experiment front counter weight 400, later carry out the scissors fork lift work platform of experiment only need remove the position that position finding component 300 detected, and lifting part 220 just can be automatic with counter weight 400 hoist and place or lift by crane and leave on the scissors fork lift work platform to improve experimental efficiency.
Optionally, the positioning element 300 is a correlation photoelectric sensor; the controller is a singlechip. Wherein, communication connection is wireless connection, and specifically, wireless connection is bluetooth connection.
As shown in fig. 1, in some embodiments, the beam 210 is provided with a first limiting member 211 and a second limiting member 212, where the first limiting member 211 and the second limiting member 212 are spaced apart and disposed opposite to each other along a first direction; 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 limiting member 211 and the second limiting member 212, and then the beam 210 is lifted. In this manner, wobble in a first direction relative to the rail 510 when the beam 210 is separated from the support assembly 100 is avoided.
Further, the first limiting member 211 is provided with a first magnetic member, the second limiting member 212 is provided with a second magnetic member, and the counterweight 400 is provided with a first magnetic attraction portion magnetically attracted to the first magnetic member and a second magnetic attraction portion magnetically attracted to the second magnetic member. Specifically, the first magnetic member is located on a side of the first limiting member 211 adjacent to the second limiting member 212, and the second magnetic member is located on a side of the second limiting member 212 adjacent to the first limiting member 211. The first magnetic attraction portion and the second magnetic attraction portion are located on two sides of the rail 510 of the aerial working platform 500 that are disposed opposite to each other in the first direction. When the rail 510 of the aerial working platform 500 contacts the first limiting piece 211 and the second limiting piece 212, the first magnetic piece and the second magnetic piece are matched with the magnetic attraction of the first magnetic attraction part and the second magnetic attraction part, so that the scissor type lifting working platform is ensured to accurately enter between the first limiting piece 211 and the second limiting piece 212. Alternatively, the magnetic member may be a magnet or a magnet; the magnetic attraction piece can be a magnetophilic metal such as iron, nickel, cobalt and the like.
In some embodiments, the beam 210 may further be provided with a fifth limiting member and a sixth limiting member, where the fifth limiting member and the sixth limiting member are spaced 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 of the scissor lift work platform in the first and second directions relative to the scissor lift work platform when the beam 210 is separated from the support assembly 100 is avoided.
In some embodiments, the first support 110 is configured to support a neutral connection at one end of the beam 210, and the second support 120 is configured to support a live connection at one end of the beam 210; the two ends of the beam 210 are respectively provided with a first conductive member and a second conductive member, and the first conductive member and the second conductive member are respectively connected with the positive electrode and the negative electrode of the lifting member 220 in a conductive manner; when the supporting assembly 100 supports the beam 210, the first conductive member is electrically contacted with the live wire connector, and the second conductive member is electrically contacted with the neutral wire connector. The lifting member 220 is connected to the circuit when the beam 210 is in contact with the support assembly 100, so that the lifting member 220 can be operated normally only when the support assembly 100 supports the beam 210. In this way, the crane 220 is prevented from lifting the counterweight 400 due to the failure of the controller in the lifting process, and the situation that the power line is broken in the lifting process when the crane 220 uses the power line to access the circuit is avoided.
As shown in fig. 7, an embodiment relates to a method for testing the weight of an aerial work platform 500, which is applied to the apparatus for testing the aerial work platform 500 as described above, and the method for testing the weight of the aerial work platform 500 includes: step S1, controlling the lifting member 220 to hoist 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, the aerial work platform 500 is controlled to descend to a second preset height, wherein the cross beam 210 contacts with 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 the step S2 and the step S3 of the preset test times; step S5, the crane 220 is started to lift the counterweight 400, so that the counterweight 400 is separated from the aerial work platform 500, and the test is completed. Thus, by the above-mentioned experimental method, the standard weight experiment of the aerial work platform 500 can be rapidly completed without moving the lifting member 220.
In this embodiment, the first preset height is a maximum lifting height of the scissor lift platform. The second preset height is the minimum height of the scissor type lifting working platform when the scissor type lifting working platform is contracted, and the preset inspection times are at least twice.
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 contracted. So that the scissor lift work platform can be moved to the position right below the standard weight to carry out experiments. When the first scissor type lifting work platform is tested, the first scissor type lifting work platform is operated to move away from the experimental area, and the second scissor type lifting work platform is tested, the height of the counterweight 400 relative to the supporting surface of the scissor type lifting work platform is not required to be adjusted, and the experimental method for the standard weight of the aerial work platform 500 can be directly carried out.
