Operation principle: with reference to fig. 5, because the two guide gears 22 are in an externally meshed state, that is, the rotation directions of the two guide gears 22 are opposite, so that the two guide gears are combined to the use process of the wire clamping wheel 15 for the wire pressing hemispherical plate 21, but on the basis, because the wire clamping wheel 15 is used as a direct stress point of the wire cable, the clamping stability of the two wire clamping wheels 15 on the wire cable needs to be ensured, and the abnormal problem caused to the motor by the first embodiment still exists only by virtue of the power of the second servo motor 14;
for this purpose, the hydraulic telescopic pump 10 is further added to control the horizontal movement of the gear rod 23, and the movement form of the gear rod 23 to the driving gear 20 through the guide gear 22 is consistent with the movement form of the driving gear 20 driven by the second servo motor 14, so that the hydraulic telescopic pump 10 mainly plays a role in deepening the clamping degree of the wire clamping wheel 15.
Example III
The present embodiment is a front structure of the second embodiment, namely, it is understood that: the operation process of the second embodiment is determined by this embodiment, and the specific manner is as follows:
the front support 17 is arranged at the position of the assembly winding box 5 corresponding to the pressed support 24, the front wheel 19 is rotatably arranged in the pressed support 24, the pressed support 24 is horizontally arranged, the pressed support 24 is in sliding connection with the front support 17 along the vertical direction, and the pressure sensor 18 is arranged at the position right below the pressed support 24.
A plurality of directional guide rods 25 are slidably arranged on the pressure-receiving support 24 along the vertical direction, the tail ends of the directional guide rods 25 are arranged in the assembly winding box 5, high-strength springs 26 are arranged on the circumferential outer walls of the directional guide rods 25, a pressure-receiving plate is arranged on the output end of the pressure sensor 18 and is positioned right below the front wheel 19, and a pressure-receiving gap is arranged between the pressure-receiving plate and the pressure-receiving support 24.
Working principle: the present embodiment needs to refer to fig. 4, and it should be noted that: the invention is only directed to the part of the wire rope in the hoisting device, and the rest of the connection modes are not described, but the front wheels 19 need to be arranged at the 'end positions' of the wire rope, and are specifically shown as follows: the wire wheel set 16 plays a role of conducting a wire rope, and the front wheel 19 is required to directly bear the weight of the hoisted article;
referring to fig. 4 and 6, when the end of the steel wire rope is bound with the hoisting article, the weight of the hoisting article can be used to represent the bearing pressure on the steel wire rope, if the pressure sensor 18 is only used for bearing the weight of the hoisting article, the use requirement on the pressure sensor 18 is extremely high, for this purpose, the front wheel 19 needs to be matched with the pressure bearing bracket 24, the pressure bearing bracket 24 directly bears the weight of the hoisting article and slides downwards, and the process needs to be described as follows:
s1: the plurality of high-strength springs 26 are required to be additionally arranged, and the bearing capacity of the high-strength springs 26 is large enough, so that the bearing capacity of a steel wire cable is replaced by the sum of the bearing capacities of each high-strength spring 26 in the actual use process, and the bearing capacity of the high-strength springs 26 mainly shows the deformation capacity when the high-strength springs 26 receive pressure;
s2: in combination with the S1 content, when the article is lifted and moves back and forth and left and right, because the lifted article is subjected to the influence of "inertia" and swings, a higher instantaneous bearing pressure is instantaneously generated on the steel wire rope, and the high-strength spring 26 is further elastically deformed when the instantaneous bearing pressure is perceived, so that the motion state generating "inertia movement" can be buffered and protected, specifically, two processes of "absorption" and "release" of the spring are utilized, and what needs to be described here is: the bearing capacity of the high-strength spring 26 does not take into account the maximum load in the drive motor assembly 9, but rather acts as a "support structure" for the pressure-bearing bracket 24;
s3: also described for S2 is: regarding the influence of the high-strength spring 26 on the setting position of the pressure receiving plate on the pressure sensor 18, in the initial state, i.e. the steel wire rope is not used for hoisting the article, the high-strength spring 26 is in a natural state in the process, and a sufficient compression gap exists between the pressure receiving plate and the compression bracket 24, if the weight of the hoisted article is low, the high-strength spring 26 is enough, the pressure receiving plate and the compression bracket 24 still do not contact, but when a large instantaneous bearing pressure is generated or the weight of the hoisted article is high, the deformation degree of the high-strength spring 26 is increased, so that the pressure receiving plate contacts the compression bracket 24, a specific pressure value is displayed on the pressure sensor 18, but the pressure value is not the weight of the hoisted article, but the "extra pressure" after the bearing capacity of the plurality of high-strength springs 26 is subtracted, so that the "extra pressure" can directly display the running state in the whole hoisting process;
it should be noted that: it is also necessary to further limit the maximum travel of the downward movement of the pressure receiving plate, i.e. the maximum display value in the pressure sensor 18, which is still determined by the bearing capacity of the high-strength spring 26, and is expressed as follows: the high-strength spring 26 reaches the maximum value when elastically deforming, and the pressure-bearing bracket 24 cannot move downwards continuously when the high-strength spring 26 reaches the maximum deformation, and the pressure borne by the steel wire rope exceeds the maximum load of the driving motor assembly 9 when the maximum deformation occurs;
the following are described in connection with the contents of S1 to S3: the specification and the number of the high-strength springs 26 can be selected according to the hoisting requirement (maximum load) of the hoisting device, and when the pressure borne by the steel wire rope exceeds the maximum load of the driving motor assembly 9, the technical content in the second embodiment needs to be utilized, specifically, the hydraulic telescopic pump 10 is used for further promoting the reinforcing process of the wire clamping wheel 15, whereas when the display value of the pressure sensor 18 does not reach the maximum display value, the reinforcing process of the hydraulic telescopic pump 10 on the wire clamping wheel 15 can be slowed down, so that according to the actual operation process, the two processes of active paying-off or passive paying-off are carried out on the steel wire rope, wherein the active paying-off process is carried out when the display value of the pressure sensor 18 does not reach the maximum display value, and the passive paying-off process is carried out when the display value of the pressure sensor 18 reaches the maximum display value.
To sum up: the stress state of the steel wire rope is divided by two wire clamping wheels, and the concrete steps are as follows: in the hoisting process, the reel is not a direct stress structure, but takes the wire clamping wheel as a direct stress point, and the purpose is that: the method is characterized in that when unexpected situations occur, the damage of a mechanical assembly caused by overlarge stress of a steel wire rope is avoided, two processes of active paying-off and passive paying-off are formed in a movement mode of a wire clamping wheel and are matched with inertial movement generated in the front-back and left-right movement process in the hoisting process, the front stress detection is carried out on the two processes on the basis of the technology, and the starting mode of the two processes is selected according to specific stress conditions.
