技术领域technical field
本实用新型涉及物料称重设备技术领域,尤其涉及一种校秤结构。The utility model relates to the technical field of material weighing equipment, in particular to a calibration scale structure.
背景技术Background technique
在一些工业生产过程中需要将不同的原料按一定配比进行配料,这种配料过程可以是连续的,也可能是分不同批次进行的,但在在分批次配料过程中需要使用配料秤对原料进行计量。配料秤作为一种衡器,需要定期校核,保证配料秤的精度在允许误差范围内。In some industrial production processes, it is necessary to batch different raw materials according to a certain ratio. This batching process can be continuous or divided into different batches, but batching scales are required in the batch batching process. Measure raw materials. As a weighing instrument, the batching scale needs to be checked regularly to ensure that the accuracy of the batching scale is within the allowable error range.
目前配料秤校秤方式有两种,一种是直接在配料秤的砝码架上或者托盘上放置需要重量的砝码对秤体进行校核,另一种是给秤体上配置需要重量的砝码或者砝码替代物,这两种方式都是使用标准砝码或者重量不变的砝码替代物进行校秤,一般的配料秤会在秤体上设置砝码架用于校秤时摆放砝码,也有的配料秤是通过提前设置吊钩,在校秤时将专用托盘挂在吊钩上并在托盘上摆放该专用砝码进行校秤,在这种情况下,校秤的砝码重量不能小于配料秤量程的75%,使用和配料秤的量程同重量的砝码进行校核最好,从而可以对配料秤的全部量程范围进行校核。At present, there are two ways to calibrate the batching scale. One is to directly place the required weight on the weight rack or tray of the batching scale to check the scale body, and the other is to configure the required weight on the scale body. Weights or weight substitutes, these two methods are to use standard weights or weight substitutes with constant weight to calibrate the scale, and the general batching scale will set a weight rack on the scale body for swinging when the scale is calibrated. Put the weights, and some batching scales also set the hooks in advance, hang the special tray on the hooks and put the special weights on the trays to calibrate the scales. In this case, the calibration of the scales The weight of the weight cannot be less than 75% of the range of the batching scale. It is best to use a weight with the same weight as the range of the batching scale for checking, so that the entire range of the batching scale can be checked.
现有校秤方式在校秤过程中需要使用的这些砝码或者其替代物通常状态下是用平台托起或者直接放地面上,当需要校秤时启动配料秤上的气缸或者液压缸,改变砝码的位置,使砝码的重量可以传递到秤体上,这种校秤方式为自动校秤方式;而直接放砝码这种校秤方式对于大型的配料秤校秤过程而言,一次需要摆放几吨重量的砝码,劳动强度非常大,而且耗费时间,此外配料秤的校核不一定一次就能完成,用标准重量的砝码标定后还要进行复核,如果复核数据不达标,则需要再次进行校秤,工作量更大。无论是自动校秤方式还是直接放砝码校秤的方式,两种校秤方式均存在如下缺点,即秤体需要长期占用砝码或者其替代物,校秤过程中使用的这些砝码或者其替代物的普遍较重,如果秤体放置在楼房内且位于较高的楼层时,这些重量都是传递在楼面上的,意味着楼面上长期承受较重的荷载,造成对土建设计的要求相应提高,此外自动校秤方式需要气缸或液压缸类的提升设备而造成投资较大,带来较高的建设成本。The weights or their substitutes that need to be used in the calibration process of the existing calibration method are usually held up by the platform or placed directly on the ground. When the calibration is required, the air cylinder or hydraulic cylinder on the batching scale is activated to change The position of the weight enables the weight of the weight to be transferred to the scale body. This calibration method is an automatic calibration method; while the calibration method of directly placing weights is a one-time calibration method for large-scale batching scales. Several tons of weights need to be placed, which is very labor-intensive and time-consuming. In addition, the calibration of the batching scale may not be completed at one time. After calibration with standard weight weights, a re-check is required. If the re-check data is not up to standard , you need to check the scale again, and the workload is even greater. Whether it is the automatic calibration method or the method of directly placing weights to calibrate the scale, both calibration methods have the following disadvantages, that is, the scale body needs to occupy weights or their substitutes for a long time, and these weights or other weights used in the calibration process The substitutes are generally heavy. If the scale body is placed in a building and is located on a higher floor, the weight is transmitted on the floor, which means that the floor bears a heavy load for a long time, causing damage to the civil engineering design. The requirements have been increased accordingly. In addition, the automatic calibration method requires lifting equipment such as cylinders or hydraulic cylinders, resulting in large investment and high construction costs.
基于此,如何提供一种低成本且不占用较多的砝码或其替代物以减轻重量的校秤装置,是目前本领域技术人员亟待解决的问题。Based on this, how to provide a low-cost calibrating device that does not take up many weights or their substitutes to reduce weight is an urgent problem to be solved by those skilled in the art.
实用新型内容Utility model content
为解决上述技术问题,本实用新型提供了一种校秤结构。In order to solve the above technical problems, the utility model provides a scale calibration structure.
为实现上述目的,本实用新型提供如下技术方案:In order to achieve the above object, the utility model provides the following technical solutions:
一种校秤结构,包括设置在秤斗支座的定滑轮组一、设置在秤架或地面且位于所述定滑轮组一下方的定滑轮组二、以及柔索,校秤结构还包括称重传感器,所述称重传感器与所述秤斗支座连接,所述定滑轮组一和所述定滑轮组二的各个滑轮的设置满足当所述柔索依次分别绕所述定滑轮组一和所述定滑轮组二的各个滑轮后所述柔索与各个滑轮非接触的各段的朝向为竖直方向,所述柔索的第一端固定在所述秤斗支座或所述秤架上,所述柔索的第二端用于悬挂重物以使所述柔索受力。A scale calibration structure, comprising a fixed pulley set 1 arranged on the scale bucket support, a fixed pulley set 2 arranged on the scale frame or the ground and located below the fixed pulley set 1, and flexible cables, the scale calibration structure also includes a load cell, The load cell is connected to the weighing bucket support, and the pulleys of the fixed pulley block 1 and the fixed pulley block 2 are set to meet the requirement that when the flexible cables respectively wind around the fixed pulley block 1 and the fixed pulley block 2 After each pulley of each pulley, the direction of each segment of the flexible cable that is not in contact with each pulley is the vertical direction, and the first end of the flexible cable is fixed on the weighing bucket support or the scale frame, and the flexible cable The second end is used for hanging heavy objects so that the flexible cable is stressed.
有益效果是:秤在原始状态下,配料秤的称架是固定在地面上的,用于支撑秤斗的秤斗支座放置在秤架上,且秤斗支座与秤架的接触位置设有称重传感器。在设置该校秤结构时,需分别在秤斗支座、秤架上设置定滑轮组一和定滑轮组二,再使用柔索依次分别绕定滑轮组一和定滑轮组二的各个滑轮后,将柔索的第一端固定在秤斗支座或秤架上,柔索的第二端用于悬挂重物。在校秤时,柔索的第二端因承重而使柔索处于受力拉直状态,由于柔索和每一个滑轮在竖直方向的切线重合,因此柔索与各个滑轮非接触的各段均为竖直方向,当在柔索的第二端悬挂重物以使柔索的第二端受力后,根据定滑轮的原理,只需要计算出设置在秤斗支座上的定滑轮个数、或者计算竖直方向上柔索绕滑轮后与各个滑轮非接触的各段的段数,就可以得出秤斗支座受力大小情况,将该受力大小与称重传感器读取的重量进行对比,即可进行校秤。通过不断调整柔索的第二端所悬挂的重物的重量,依次重复该过程即可完成校秤。该校秤结构可以通过定滑轮组对秤斗支座的受力进行倍数放大,利用比配料秤量程范围小的重物即可以实现对量程较大的配料秤进行校秤的目的,解决了校秤过程中需满足重物总重接近配料秤量程的条件而导致一次校秤过程使用重物例如砝码太多的问题,同时减轻校秤工作人员的劳动强度。除此之外,该校秤结构只需在原有秤体的基础上进行改造即可,结构简单实用性强。The beneficial effect is: when the scale is in the original state, the weighing frame of the batching scale is fixed on the ground, the weighing bucket support for supporting the weighing bucket is placed on the weighing frame, and the contact position between the weighing bucket support and the weighing frame is set. There are load cells. When setting up the school scale structure, it is necessary to set the fixed pulley group 1 and the fixed pulley group 2 on the scale bucket support and the scale frame respectively, and then use the flexible cable to wind the pulleys of the fixed pulley group 1 and the fixed pulley group The first end of the cable is fixed on the scale bucket support or the scale frame, and the second end of the cable is used to hang heavy objects. When calibrating the scale, the second end of the flexible cable is in a state of stress and straightening due to the load-bearing. Since the tangent line between the flexible cable and each pulley in the vertical direction coincides, the sections of the flexible cable that are not in contact with each pulley They are all in the vertical direction. When a heavy object is hung on the second end of the flexible cable so that the second end of the flexible cable is stressed, according to the principle of the fixed pulley, it is only necessary to calculate the number of fixed pulleys arranged on the support of the scale bucket. count, or calculate the number of sections in the vertical direction that are not in contact with each pulley after the flexible cable winds around the pulley, you can get the force of the scale bucket support, and compare the force with the weight read by the load cell For comparison, the scale can be calibrated. By constantly adjusting the weight of the weight suspended by the second end of the cable, repeating this process successively can complete the calibration. The structure of the calibration scale can multiply the force of the support of the scale bucket through the fixed pulley group, and the purpose of calibrating the scale of the batching scale with a larger range can be realized by using a heavy object with a smaller range than the batching scale, which solves the problem of calibrating the scale. The process needs to meet the condition that the total weight of the heavy objects is close to the range of the batching scale, which leads to the problem of using heavy objects such as too many weights in a calibration process, and at the same time reduces the labor intensity of the calibration staff. In addition, the school scale structure only needs to be modified on the basis of the original scale body, and the structure is simple and practical.
作为进一步地改进,所述定滑轮组一和所述定滑轮组二的各个滑轮的固定支座在水平方向上的位置可以调节,所述秤斗支座和/或所述秤架上设有用于连接柔索第一端的固定部,所述固定部在水平方向上的位置可以调节。As a further improvement, the positions of the fixed supports of the fixed pulleys of the fixed pulley group 1 and the fixed pulley group 2 in the horizontal direction can be adjusted. The fixing part at the first end of the cable, the position of the fixing part in the horizontal direction can be adjusted.
有益效果是:由于在定滑轮安装时精度不易保证,或校秤结构频繁使用,从而当柔索在绕各个滑轮后,与滑轮非接触的柔索的各段无法保持竖直状态,导致校秤结构无法保证校核精度。此时可以通过调节滑轮所对应的固定支座在水平方向上的位置,并调节用于固定柔索第一端的固定部在水平方向上的位置,以使柔索保持竖直状态,从而使校秤结构通过上述简单的调节方式就可以保证校秤精度,极大地提高了生产现场的校秤效率。The beneficial effects are: because the accuracy is not easy to guarantee when the fixed pulley is installed, or the calibration scale structure is frequently used, so that when the flexible cable winds around each pulley, each section of the flexible cable that is not in contact with the pulley cannot maintain a vertical state, resulting in the calibration of the scale. The structure cannot guarantee the calibration accuracy. At this time, the position of the fixed support corresponding to the pulley can be adjusted in the horizontal direction, and the position of the fixing part for fixing the first end of the flexible cable can be adjusted in the horizontal direction, so that the flexible cable remains vertical, so that The structure of the calibration scale can ensure the accuracy of the calibration scale through the above-mentioned simple adjustment method, which greatly improves the efficiency of the calibration scale at the production site.
作为进一步地改进,所述柔索的第二端连接托盘,所述托盘用于放置砝码。As a further improvement, the second end of the cable is connected to a tray, and the tray is used for placing weights.
有益效果是:使柔索用于悬挂重物的第二端连接托盘后,便于在校秤时直接将砝码或砝码替代物直接放入托盘,并根据校秤范围进行砝码的增减,在托盘内直接增减砝码的方式有助于提高校秤的便携性。The beneficial effect is: after the second end of the flexible cable used for hanging heavy objects is connected to the tray, it is convenient to directly put the weight or weight substitute directly into the tray when the scale is calibrated, and the weight can be increased or decreased according to the scale calibration range , The method of directly adding or subtracting weights in the tray helps to improve the portability of the calibration scale.
作为进一步地改进,所述柔索的第二端与所述托盘使用挂钩连接。As a further improvement, the second end of the cable is connected to the pallet using a hook.
有益效果是:使用挂钩将柔索的第二端与托盘连接,在校秤时可以直接将托盘挂在挂钩上,校秤结束后也便于将托盘从挂钩上拿下,挂钩结构方便了托盘使用的操作。The beneficial effect is: use the hook to connect the second end of the cable with the pallet, and the pallet can be directly hung on the hook when the scale is calibrated, and the pallet can be easily removed from the hook after the scale calibration is completed, and the hook structure facilitates the use of the pallet operation.
作为进一步地改进,还包括用于存放砝码的置物框,所述置物框设置在所述秤架上。As a further improvement, a storage frame for storing weights is also included, and the storage frame is arranged on the weighing frame.
有益效果:由于要经常进行校秤,为方便拿取砝码而直接将砝码放置在秤体周围,在秤架上设置专门用于放置砝码的置物框,在方便取用砝码的同时还可以降低砝码丢失的风险。Beneficial effects: since the scale needs to be calibrated frequently, the weights are directly placed around the scale body for the convenience of taking the weights, and a storage box specially used for placing the weights is set on the scale frame, which is convenient for taking the weights at the same time It also reduces the risk of losing weights.
作为进一步地改进,所述柔索为钢丝绳。As a further improvement, the flexible cable is a steel wire rope.
有益效果是:钢丝绳具有更好的强度,可以最大限度地防止校秤过程中断裂的发生。The beneficial effect is that the steel wire rope has better strength and can prevent fractures in the process of calibrating the scale to the greatest extent.
作为进一步地改进,所述钢丝绳的直径与所述定滑轮组一和所述定滑轮组二的各个滑轮的凹槽深度相等。As a further improvement, the diameter of the steel wire rope is equal to the groove depth of each pulley of the first fixed pulley block and the second fixed pulley block.
有益效果是:在钢丝绳绕定滑轮组一和定滑轮组二中的各个滑轮后,如果钢丝绳的直径明显大于滑轮的凹槽的深度,即使通过调整各个滑轮的水平位置,仍然容易导致与各个滑轮非接触的钢丝绳的各段无法精确地保持竖直方向而影响受力分析,进而对校秤结果造成较大的影响。而若使钢丝绳的直径与滑轮的凹槽深度相等,则在布置各个滑轮的水平位置时只需要依次使滑轮组一和定滑轮组二中的各个滑轮的凹槽在竖直方向上重合即可,这样即可以使位于滑轮凹槽之外与滑轮非接触的钢丝绳保持竖直方向,最终提高校秤的准确度。The beneficial effect is: after the wire rope winds around each pulley in the fixed pulley block 1 and the fixed pulley block 2, if the diameter of the wire rope is obviously larger than the depth of the groove of the pulley, even if the horizontal position of each pulley is adjusted, it is still easy to cause non-contact with each pulley Each segment of the steel wire rope cannot accurately maintain the vertical direction and affect the force analysis, which in turn has a greater impact on the calibration results. And if the diameter of the wire rope is equal to the groove depth of the pulley, then when arranging the horizontal position of each pulley, it is only necessary to make the grooves of each pulley in the pulley block 1 and the fixed pulley block 2 overlap in the vertical direction in turn, so that That is to say, the steel wire rope outside the groove of the pulley and not in contact with the pulley can be kept in a vertical direction, and finally the accuracy of the scale can be improved.
作为进一步地改进,所述秤斗支座上设有用于放置砝码的砝码架,以用于在校秤完成后向所述砝码架内放入砝码进行复核。As a further improvement, the weighing bucket support is provided with a weight rack for placing weights, so as to put weights into the weight rack for rechecking after the calibration of the scale is completed.
有益效果是:通过在秤斗支座上设置专门用于放置砝码的砝码架,以用于在校秤步骤完成后对上述校秤结果进行复核,由于称重传感器称重数值为与秤斗支座和秤斗的总重量,而砝码架直接设置在秤斗支座上,因此只要向砝码架内放入砝码,称重传感器即可进行称重复核,该复核过程并没有通过使用定滑轮结构进行受力倍数的放大,因此该复核过程主要复核配料秤较小一段量程范围的称重是否准确,从而进一步提高校秤的准确性。The beneficial effect is: by setting a weight frame specially used for placing weights on the scale bucket support, it is used to check the above-mentioned calibration results after the calibration step is completed, because the weighing value of the load cell is the same as the scale The total weight of the bucket support and the scale bucket, and the weight frame is directly set on the scale bucket support, so as long as the weight is put into the weight frame, the load cell can carry out weighing and rechecking, and the rechecking process does not The fixed pulley structure is used to amplify the force multiple, so the review process mainly reviews whether the weighing in the smaller range of the batching scale is accurate, so as to further improve the accuracy of the calibration scale.

A simple machine that can rotate around a central axis, consisting of a grooved disc that can rotate around a central axis and a flexible cable (rope, tape, cable, chain, etc.) that spans the disc, is called a pulley. When using a pulley, the pulley whose shaft position is fixed is called a fixed pulley.
为更好地理解本实用新型,下面将结合附图对本发明的实施例进行阐述。In order to better understand the utility model, the embodiments of the invention will be described below in conjunction with the accompanying drawings.
如图1所示,一种校秤结构,主要包括定滑轮组一2、定滑轮组二4、柔索5、称重传感器6。As shown in Fig. 1, a kind of scale calibration structure mainly includes fixed pulley block one 2, fixed pulley block two 4, flexible cable 5, weighing
其中,定滑轮组一2设置在秤斗支座1上,定滑轮组二4设置在秤架3或地面上,且定滑轮组二4位于定滑轮组一2的下方,柔索5依次分别绕定滑轮组一2和定滑轮组二4的各个滑轮,在柔索5绕各个滑轮后,柔索5的第一端51固定在秤斗支座1或秤架3上,柔索5的第二端52用于悬挂重物以使柔索5受力,而称重传感器6设置在秤架3与秤斗支座1之间,以对秤斗支座1的重量、以及施加在秤斗支座1上的其他外力换算成对应的重量的重量总和进行读取。Among them, the fixed pulley group 1 2 is arranged on the scale bucket support 1, the fixed pulley group 2 4 is arranged on the
由于该校秤结构要利用定滑轮的原理,故需要使定滑轮组一2和定滑轮组二4的各个滑轮的设置满足当柔索5依次分别绕定滑轮组一2和定滑轮组二4的各个滑轮后,柔索5和与每一个滑轮在竖直方向的切线重合。Because the school scale structure will utilize the principle of the fixed pulley, it is necessary to make the setting of each pulley of the fixed pulley block 2 and the fixed pulley block 2 4 meet the requirements when the flexible cables 5 respectively wind around the pulleys of the fixed pulley block 2 and the fixed pulley block 2 4 respectively. , flexible cable 5 coincides with the tangent of each pulley in the vertical direction.
由于各个滑轮在竖直方向具有两条切线,而柔索5与每一个滑轮非接触的各段亦形成两条直线,这两条直线所在方向需与上述两条切线重合,才可以满足柔索5与各个滑轮非接触的各段的朝向为竖直方向。具体地,这里可以使柔索5的直径与定滑轮组一2和定滑轮组二4的各个滑轮的凹槽深度相等,在布置各个滑轮的水平位置时只需要依次使滑轮组一和定滑轮组二中的各个滑轮的凹槽在竖直方向上重合即可,这样就可以使位于各个滑轮凹槽之外与对应滑轮非接触的柔索5保持竖直方向。Since each pulley has two tangents in the vertical direction, and the sections of the cable 5 that are not in contact with each pulley also form two straight lines, the directions of these two straight lines must coincide with the above two tangents to satisfy the requirements of the cable. 5. The orientation of each segment that is not in contact with each pulley is the vertical direction. Specifically, the diameter of the cable 5 can be made to be equal to the depth of grooves of each pulley of the fixed pulley block one 2 and the fixed pulley block two 4. When arranging the horizontal position of each pulley, it is only necessary to make the pulley block one and the fixed pulley block two in turn. The grooves of each pulley can overlap in the vertical direction, so that the cable 5 that is not in contact with the corresponding pulley outside the groove of each pulley can be kept vertical.
可以理解的是,柔索5与各个滑轮的布置要求只要满足柔索5与各个滑轮非接触的各段保持竖直方向即可,而对定滑轮组一2中的各个滑轮的高度是否一致不做要求,同理,定滑轮组二4中的各个滑轮的高低位置也可以是不同的,这里对具体某一个定滑轮组内的各个滑轮的高低不做特别的限制。只要定滑轮组一2中的各个滑轮的高度高于定滑轮组二4中的各个滑轮的高度即可。It can be understood that the arrangement requirements of the cable 5 and each pulley only need to meet the requirement that the sections of the cable 5 and the pulleys are not in contact with each other to maintain a vertical direction, and it does not matter whether the heights of the pulleys in the fixed pulley block-2 are consistent. Requirement, likewise, the height position of each pulley in the fixed pulley block two 4 also can be different, here does not do special restriction to the height of each pulley in the specific certain fixed pulley block. As long as the height of each pulley in the fixed pulley block one 2 is higher than the height of each pulley in the fixed pulley block two 4, it gets final product.
为进一步保证钢丝绳与各个滑轮凹槽之外与对应滑轮非接触的各段保持竖直方向,或更易于调整定滑轮组一2、定滑轮组二4、柔索5以满足上述设置要求,还可以将定滑轮组一2和定滑轮组二4的各个滑轮的固定支座在水平方向上的位置设计成可以调节的结构,同时将秤斗支座1和/或秤架3上设置的用于连接柔索5的第一端51的固定部7在水平方向上的位置也设计成可以调节的结构。这里可以在秤斗支座1和秤架3上设置水平滑轨,并使各个滑轮的固定支座的底部具有与滑轨配合的滑动块,同时还可以在水平滑轨上设置用于固定滑动块的锁止螺栓。In order to further ensure that the steel wire rope maintains a vertical direction with each section that is not in contact with the corresponding pulley except for each pulley groove, or it is easier to adjust the fixed pulley block one 2, the fixed pulley block two 4, and the flexible cable 5 to meet the above-mentioned setting requirements. The position of the fixed bearings of each pulley of the fixed pulley group one 2 and the fixed pulley group two 4 in the horizontal direction is designed as a structure that can be adjusted. The horizontal position of the fixed portion 7 of the
在实际校秤过程中,柔索5的第二端52可以连接一个托盘8,具体地可以在第二端52处固定一个挂钩,并使用挂钩将托盘8钩起,托盘8主用用来放置砝码或砝码替代物。In the actual scale calibration process, the
上述各实施例中的柔索5可以是钢丝绳。The flexible cables 5 in the above-mentioned embodiments can be steel wire ropes.
在其他实施例中,还在秤架3上设置了用于存放砝码的置物框。置物框只要满足能够盛放校秤过程中使用的砝码或砝码替代物即可。In other embodiments, a storage frame for storing weights is also provided on the
在另外一些实施例中,还在秤斗支座1上设置了用于放入砝码的砝码架,以用于在校秤完成后向砝码架内放入砝码进行复核。这里砝码架需与秤斗支座固定连接,才能在复核时通过称重传感器显示此时的称重重量,进而将称重传感器读取的重量值与已放入砝码架内的砝码重量进行对比并复核。In some other embodiments, a weight rack for putting in weights is also provided on the scale bucket support 1, so as to put weights into the weight rack for rechecking after the calibration of the scale is completed. Here, the weight frame needs to be fixedly connected with the scale bucket support, so that the weighing weight at this time can be displayed through the load cell during the recheck, and then the weight value read by the load cell can be compared with the weight that has been placed in the weight frame. Compare the weights and double check.
