Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

As shown in fig. 1 to 4, the cage of the present invention includes a frame body 310, a cage body 320, a folding ladder 330, and a first driving member 340; the frame body 310 is used for connecting to the rotary table 600 of the crane and is provided with a first hinge point; the cage body 320 is disposed on the frame body 310; one end of the folding ladder 330 is hinged at the first hinge point and the other end is a free end to be movable between a folded state and an unfolded state; the first driving member 340 is configured to drive the folding ladder 330 to rotate around the first hinge point; wherein, in the folded state, the free end is far away from the ground; in the open state, the free end is close to the ground.

In the utility model, when the operator does not need to enter or exit the control cabin body 320, the folding ladder 330 is in a folded state, and in the folded state, the free end of the folding ladder 330 is far away from the ground, so that the traveling of the crane is not influenced; when the operator needs to get in and out of the cage body 320, the crane stops running, and the folding ladder 330 is switched to the open state in which the free end is close enough to the ground or even in contact with the ground, so that the operator can climb from the ground into the cage body 320 or descend from the cage body 320 to the ground. Therefore, the utility model discloses a control cabin can make things convenient for operating personnel's business turn over, guarantees operating personnel's personal safety.

It should be appreciated that the first actuator 340 may take various forms to actuate the folding ladder 330 to rotate about the first hinge point, for example, the first actuator 340 may be a linear cylinder, and in this embodiment, in the folded state, the folding ladder 330 is disposed substantially perpendicular to the ground, and therefore, the linear cylinder is disposed at an angle to the folding ladder 330 in the folded state so as to generate a moment to actuate the folding ladder 330 to switch to the unfolded state.

It should be understood that the folding ladder 330 may be designed in various forms as long as it can be switched between the folded state and the unfolded state. In one embodiment of the present invention, the folding ladder 330 includes a main ladder 331 and an auxiliary ladder 332; one end of the main ladder 331 is hinged to the first hinge point, and the other end can rotate around the first hinge point and is provided with a second hinge point; one end of the auxiliary ladder 332 is hinged to the second hinge point and the other end is a free end. The benefit that sets up like this is, under fold condition, the folding ladder 330 can keep shorter height to be convenient for going of hoist, and under open mode, the folding ladder 330 can have the length sum of main ladder 331 and vice ladder 332, can make the free end of vice ladder 332 contact ground more easily, makes things convenient for operating personnel's climbing, has also improved the security of climbing greatly.

In addition, in order to make the folding ladder 330 have a smaller volume in the folded state, in an embodiment of the present invention, the bottom surface of the main ladder 331 has an accommodation space capable of accommodating the auxiliary ladder 332, and in the folded state, the auxiliary ladder 332 is placed in the accommodation space. Here, the bottom surface of the main ladder 331 is an opposite surface of the top surface having steps for an operator to climb.

In order to facilitate the climbing of the operator, optionally, the folding ladder 330 further includes a limiting structure, and the limiting structure is configured to limit the rotation angle of the main ladder 331, so that the included angle between the main ladder 331 and the ground in the opened state is limited to 30 to 50 degrees, and since the main ladder 331 is not perpendicular to the ground, the walking and climbing of the operator on the main ladder 331 will be more labor-saving.

Therefore, in the above embodiment, the folding ladder 330 is configured to: in the folded state, the auxiliary ladder 332 coincides with the main ladder 331 and the free end of the auxiliary ladder 332 is away from the ground, i.e., the auxiliary ladder 332 is received in the receiving space of the main ladder 331; and in the open state, the main ladder 331 forms an angle of 30 to 50 degrees with the ground, the auxiliary ladder 332 is perpendicular to the ground, and the free end is close to the ground or even contacts the ground.

In some situations, the height that the operator needs to climb may be relatively high, for example, the operator needs to climb up the cab body 320 of the crane from the tunnel, and the bottom of the tunnel is relatively far from the cab body 320, which may result in a long overall length of the folding ladder 330 in the folded state, and may affect the traveling crane. To solve this problem, in an embodiment of the present invention, the auxiliary ladder 332 is configured such that the free end thereof can be extended and contracted in the length direction of the auxiliary ladder 332. That is, in folded state, the overall length of the folding ladder 330 can not be lengthened, the auxiliary ladder 332 is set to be the ladder of the telescopic structure, the overall width of the folding ladder 330 is increased only to a certain extent, adverse effects can not be caused to the traveling crane, and when an operator needs to climb to a higher height, the auxiliary ladder 332 is fully extended out to meet the height requirement.

In order to further ensure the personal safety of the operator when climbing the folding ladder 330, optionally, the main ladder 331 further comprises a step portion 3311 and a first guardrail 3312 disposed on the step portion 3311, one end of the step portion 3311 is hinged to the first hinge point, and the other end can rotate around the first hinge point and is provided with a second hinge point. The first guard rail 3312 can prevent the operator from falling off the main ladder 331, and the safety is improved.

In addition, when the operator is at the level of the cage body 320, in order to prevent the operator from falling down or falling down when entering or exiting the cage body 320, optionally, the frame body 310 further includes a second protection fence 311 disposed outside the cage body 320, and the second protection fence 311 is spaced apart from the cage body 320 so as to allow the operator to walk between the second protection fence 311 and the cage body 320.

The utility model also provides a control room movement mechanism, which comprises a swing arm 100, a second driving piece 400 and the control room; one end of the swing arm 100 is connected with the frame body 310 of the control room, and the other end of the swing arm 100 is a hinged end which is used for being hinged with the rotating platform 600 of the crane; the second driver 400 is configured to drive the swing arm 100 to rotate about the hinge end in the horizontal direction. This control cabin motion has consequently also had the advantage that operating personnel passed in and out the control cabin convenience, security are high owing to adopted the utility model discloses a control cabin.

In addition, the cage 310 is hinged to one end of the swing arm 100, and the third driving member 200 is configured to drive the cage 310 to rotate in a horizontal direction. Through setting up second driving piece 400 and third driving piece 200, the utility model discloses a control room motion can arrange the control room in the rear portion of revolving stage 600 when the hoist driving, does not influence the restriction of driving width to can arrange the control room in the side of revolving stage 600 (being side of hoist) when the hoist carries out the operation, the operating personnel in the control room of being convenient for observes, operates.

The utility model also provides a hoist, hoist include revolving stage 600 and foretell control cabin motion, and the articulated end of control cabin motion's swing arm 100 articulates to revolving stage 600. The crane adopts the control cabin and the control cabin movement mechanism, so that the advantages of the control cabin relative to the prior art are the same, and the description is omitted.
